External subscriber lists in 2.1
by J C Lawrence 24 Aug '02

24 Aug '02

Barry, In 2.1 when used with external subscriber storage (eg SQL), will the new equivalent of qrunner request and load the entire subscriber DB onto the heap prior to broadcast? <<Yeah, I'm cheating and being lazy on not checking the source myself>> Reason: This poses scaling problems for lists with very large numbers of subscribers. I'd suggest paging thru the set in blocks. ObExcuse: Chap on -users asking about millions of subscribers. -- J C Lawrence ---------(*) Satan, oscillate my metallic sonatas. claw(a)kanga.nu He lived as a devil, eh? http://www.kanga.nu/~claw/ Evil is a name of a foeman, as I live.

Initial Mailman v2.0 with TMDA and Mime filtering
by J C Lawrence 24 Aug '02

24 Aug '02

This is mostly written for the Mailman MLM community, but is CCed to tmda-users as it applies there as well. In general subsequent discussion should happen on mailman-developers, so I've set Reply-To accordingly. I'm writing this now as the discussed configuration appears to work and I'd rather document it now while its still fresh in my mind then later when its not. If any big bugs or required changes surface I'll post on those later to the mailman-developers list. I built the system with Mailman 2.0, TMDA 0.58, Exim v3, mimefilter, mimedecode, and procmail. You don't need mimedecode or mimefilter, but if you want to do mime filtering (even with say strip mime or demime instead) adapting the below is should be simple and obvious. Several aspects and details are going to be specific to the default configurations and installations of the relevant packages under Debian Linux. I will assume that you'll be Linux/Unix savvy enough to both detect those points and work around them as needed. Background: -- I decided to integrate the system via procmail as I also wanted to (easily) add MIME filtering and other forms of message rewriting to my list setup. -- A primary goal is that the system operates without requiring either SysAdm or list owner attention. -- As discussed on-list One of my wishes was that lists maintain whitelists which are private to them and thus not shared across the entire set of lists serviced by that host. I will not detail how I went about that except in passing as current TMDA development initiatives will render that much simpler in future. -- Elegance was not a goal. Workability and were. There are several rough edges left. Some are noted below. How-To: ------- Getting the system working essentially has three steps: 1) Getting Mailman working transparently under Exim without aliases. 2) Getting TMDA configured, installed, and tested. 3) Getting TMDA integrated with Exim and Mailman, using procmail as a glue layer. You'll be wise to check and test each step as you go along. Finding the correct source of faults with the whole system in place can be a confusing and difficult exercise. Its easier to test and retest as you go along so as to limit the set of possible items that need examination for error. Step one is fairly simple: Just configure Exim as per the README.Exim or Nigel's HOW-TO on exim.org. Make sure its all working and that Mailman functions correctly in all regards as regards the MTA. You will have to update and extend these configurations later to suit TMDA, but start out making sure you have the base right. If Mailman doesn't work on your system its hardly worth trying to get TMDA also not working. Install TMDA on your system (Debian uses a $PREFIX of /usr). Make sure you get at least version 0.58. For Debian this means installing from /testing. If you use a later version (such as current CVS) read the changelog carefully as you'll have to make some adaption in your setup to the new features in TMDA. Those changes are left as an exercise for the reader. Under ~list/ creat the following directory hierarchy, with 0700 permissions and owned by list.list (the Debian Mailman user): ~list/.tmda ~list/.tmda/cache ~list/.tmda/lists ~list/.tmda/logs ~list/.tmda/filters ~list/.tmda/pending ~list/.tmda/templates Within that tree creat the following empty files, each of zero length, owned by list.list and with 0600 permissions: ~list/.tmda/lists/released ~list/.tmda/lists/whitelist.auto ~list/.tmda/lists/blacklist ~list/.tmda/lists/whitelist ~list/.tmda/filters/outgoing The above files need to be created as otherwise TMDA will error when it fails to find them. If you have particular scaling or performance issues with regard to these address lists you might want to use the dbm or cdb forms instead (see the TMDA documentation for details). If so, make sure you configure ~list/.tmda/config to match. Next copy the default TMDA message templates to: ~list/.tmda/templates/bounce.txt ~list/.tmda/templates/confirm_request.txt ~list/.tmda/templates/confirm_accept.txt And rewrite them as suitable for your mailing lists. Now create your TMDA crypt key in: ~list/.tmda/crypt_key and your TMDA configuration in: ~list/.tmda/config My ~list/.tmda/config reads: DATADIR = "/var/lib/mailman/.tmda/" MAIL_TRANSFER_AGENT = "exim" DELIVERY = "|/usr/bin/procmail -p -f $SENDER" RECIPIENT_DELIMITER = "+" CRYPT_KEY_FILE = "/var/lib/mailman/.tmda/crypt_key" BARE_APPEND = "/var/lib/mailman/.tmda/lists/whitelist" CONFIRM_APPEND = "/var/lib/mailman/.tmda/lists/whitelist.auto" CONFIRM_MAX_MESSAGE_SIZE = None TEMPLATE_DIR = "/var/lib/mailman/.tmda/templates/" ACTION_INCOMING = "confirm" ACTION_OUTGOING = "bare" FINGERPRINT = ["message-id", "from", "date"] FULLNAME = "List Filter System" HOSTNAME = "kanga.nu" LOGFILE_DEBUG = "/var/lib/mailman/.tmda/logs/tmda_debug.log" LOGFILE_INCOMING = "/var/lib/mailman/.tmda/logs/tmda_incoming.log" PENDING_BLACKLIST_APPEND = "/var/lib/mailman/.tmds/lists/blacklist" PENDING_BLACKLIST_APPEND = "/var/lib/mailman/.tmds/lists/deleted" PENDING_RELEASE_APPEND = "/var/lib/mailman/.tmda/lists/released" PENDING_WHITELIST_APPEND = "/var/lib/mailman/.tmda/lists/whitelist" TIMEOUT = "2w" You'll specifically need to tailor the values of FULLNAME and HOSTNAME from the above cases. Note: I use a RECIPIENT_DELIMITER of "+" as I use "-" in several list names and don't want the two appearing to run together. Make sure you read the caveats on using "+" in the TMDA FAQ before chosing the RECIPIENT_DELIMITER you want to use. In my case ~list/.tmda/logs is actually a symlink to /var/log/TMDA which is owned by list.list and of 0700 permissions and a matching logrotate stanza: /var/log/TMDA/procmail.log { monthly compress missingok } /var/log/TMDA/tmda-debug.log { monthly compress missingok } /var/log/TMDA/tmda-incoming.log { monthly compress missingok } Next, and almost finally is to create the incoming filter with ownership list.list and permissions 0600: ~list/.tmda/filters/incoming The contents should be similar to: # # Note: First match wins, so sequence of rules is significant # # # Bounce blacklisters # from-file ~list/.tmda/lists/blacklist bounce # # Explicitly listed whitelist addresses get thru (explicitly because # this is a hand maintained file) # from-file ~list/.tmda/lists/whitelist ok # # Normal list members get thru. Repeat this line as needed for each # of your lists, replacing "listname" with each listname. # from-mailman -attr=members ~list/lists/listname ok # # Digest members get thru. Repeat this line as needed for each of # your lists, replacing "listname" with each listname # from-mailman -attr=digest_members ~list/lists/listname ok # # Confirmed whitelist addresses get thru (the whitelist.auto file is # built by posters confirming themselves to TMDA) # from-file ~list/.tmda/lists/whitelist.auto ok # # Mail from the list control gets thru. Repeat these lines as needed # for each of your lists, replacing "listname" with each listname. # from listname-admin(a)kanga.nu ok from listname-owner(a)kanga.nu ok Tailor to suit as noted. Soon the complexity (and hand effort of adding the list-specific lines) will no longer be necessary as future versions of TMDA will have a more flexible filter schema that supports variable replacement. At this point you should be able to test your TMDA configuration (not including the Mailman specific bits), manually injecting messages into tmda-inject while having the environment variables SENDER and RECIPIENT appropriately set and seeing that it doesn't error (check the bounces and ~list/.tmda/logs/tmda-debug.log for specifics on errors). Check your TMDA setup carefully and pay particular attention to file permissions and ownership errors. Make sure you do all your testing as the Mailman user ("list" for Debian). You're now ready for the last step: integrating TMDA with Exim via procmail. Place the procmail rc in: ~list/.procmailrc Again, the ownership is list.list and permissions 0600. It should read something like: VERBOSE=off SHELL=/bin/sh PATH=/usr/bin:/usr/local/bin:/usr/lib:/usr/local/lib LOGFILE=/var/log/TMDA/procmail.log MAILDIR=/var/lib/mailman/locks # # Commands don't get filtered # :0 w * ACTION ?? mailcmd |/var/lib/mailman/mail/wrapper $ACTION $TARGET # # Pass bounces thru directly. # :0 w * ACTION ?? mailowner * ^Return-path: <> | /var/lib/mailman/mail/wrapper $ACTION $TARGET # # Mail that has already been filtered by TMDA.

If you want # list-specific inbound filters instead globally shared lists, # insert a small script here which writes a message customised # inbound filter in (say) /tmp/tmda-inbound.$$, call tmda-filter # with a matching -I argument, and then delete the temporary inbound # filter afterwards. # :0 w | /usr/bin/tmda-filter -c /var/lib/mailman/.tmda/config # # Take the exit code from TMDA. This allows procmail to return in # error to the MTA. # EXITCODE=$? Notes: 1) Please use a different loop detection header than X-Mail-Filter-Recipient. Make something up that fits your needs. 2) The added loop detection will not be necessary with TMDA versions after 0.58 as they add their own custom header which you can use for host and recipient specific loop detection. As I do want to do MIME and other message pre-processing, and I want the ability to send messages which bypass the MIME filters, my ~list/.procmailrc is a little more complex. Adapt as appropriate to your installation: VERBOSE=off SHELL=/bin/sh PATH=/usr/bin:/usr/local/bin:/usr/lib:/usr/local/lib LOGFILE=/var/log/TMDA/procmail.log MAILDIR=/var/lib/mailman/locks # # Commands don't get filtered # :0 w * ACTION ?? mailcmd |/var/lib/mailman/mail/wrapper $ACTION $TARGET # # Pass bounces thru directly. # :0 w * ACTION ?? mailowner * ^Return-path: <> | /var/lib/mailman/mail/wrapper $ACTION $TARGET # # Mail that has already been filtered by TMDA.

I could have done all that inside procmail (and probably should have). I didn't for purely historical reasons. mimedecode is a little tool which flattens quoted-printable into US ASCII. I find it rather useful. Take care here if you have posters posting with other character sets. As always: caveat emptor. At this point you should be able to test your procmail and TMDA configuration my injecting messages into procmail as below: # List posts cat message_file | procmail -mpt ACTION='post' TARGET='listname' ~list/.procmailrc # -request commands cat message_file | procmail -mpt ACTION='mailcmd' TARGET='listname' ~list/.procmailrc # -admin and -owner messages cat message_file | procmail -mpt ACTION='mailowner' TARGET='listname' ~list/.procmailrc Test it all out. Make sure TMDA is properly holding messages. Release, whitelist, blacklist etc them via: tmda-pending -c ~list/.tmda/config and watch the contents of ~list/.tmda/lists to ensure that the right things are happening. Work the whole system until you're certain that everything in the procmailrc and your TMDA configuration has been exercised and shown correct. Don't forget to go back and delete all your test addresses from the files under ~list/.tmda/lists. Remember to NOT delete the files and to do all your testing as the list user (file permissions are critical). You're now ready for the last step: Integrating with your MTA. Before we get to the message details some discussion on why I used Exim for this: I started out wanting and trying to use Postfix. The core problem I hit was making the filter process hung off the alias execute as the right user. I needed it to execute as the list user so it would be able to read the Mailman list configurations to verify subscribers from there. If you want to entirely separate posting rights from list subscription this wouldn't be a problem (just remove the mailman bits from ~list/filters/incoming). Getting the filter process to execute as 'list' under postfix proved a bitch. Its not impossible, but it requires either messing with content filters (which have a high performance overhead for ALL messages) or doing a vtable setup with a custom transport, which requires that you run your lists from a sub-domained virtual host (eg lists.kanga.nu). I am unwilling to make either compromise. YMMV. Exim conversely makes defining the specific effective UID and GID for an alias filter process very easy. I also like, know, and use Exim on other systems, so moving my list server back to Exim was no great pain. I don't like and refuse to use either Sendmail, and so can't comment on how TMDA may be integrated with it. I'm also not a QMail user and so can't comment for similar reasons. For those familiar with those respective MTAs you should be able to base off the below recipes (with the above caveats) successfully. The full set of Mailman-specific sections needed in /etc/exim/exim.conf are as below. Compare them carefully with the Nigel's HOW-TO for basic Exim/Mailman integration. The changes aren't large but you should understand each of them. The documentation at exim.org is excellent. These configurations are mildly Exim v3 specific. Exim v4 is noticeably but not fundamentally different. Use the documentation at exim.org to guide you thru the differences. In the main configuration section: # Add the Mailman user (list) to the value of trusted users so # procmail can use -p to pass environment variables through # (required by TMDA) trusted_users = mail:list # $HOME dir for Mailman MAILMAN_HOME=/var/lib/mailman # Wrapper script for Mailman MAILMAN_WRAP=MAILMAN_HOME/mail/wrapper # UID and GID for Mailman MAILMAN_UID=list MAILMAN_GID=mail In the transports section: list_transport: driver = pipe command = /usr/bin/procmail -mpt ACTION='post' TARGET='${lc:$local_part}' MAILMAN_HOME/.procmailrc # command = MAILMAN_WRAP post ${lc:$local_part} current_directory = MAILMAN_HOME home_directory = MAILMAN_HOME user = MAILMAN_UID group = MAILMAN_GID return_path_add delivery_date_add envelope_to_add environment = EXTENSION=${substr_1:$local_part_suffix}:\ RECIPIENT=$local_part$local_part_suffix@$domain list_request_transport: driver = pipe command = /usr/bin/procmail -mpt ACTION='mailcmd' TARGET='${lc:$local_part}' MAILMAN_HOME/.procmailrc # command = MAILMAN_WRAP mailcmd ${lc:$local_part} current_directory = MAILMAN_HOME home_directory = MAILMAN_HOME user = MAILMAN_UID group = MAILMAN_GID return_path_add delivery_date_add envelope_to_add environment = EXTENSION=${substr_1:$local_part_suffix}:\ RECIPIENT=$local_part$local_part_suffix@$domain list_admin_transport: driver = pipe command = /usr/bin/procmail -mpt ACTION='mailowner' TARGET='${lc:$local_part}' MAILMAN_HOME/.procmailrc # command = MAILMAN_WRAP mailowner ${lc:$local_part} current_directory = MAILMAN_HOME home_directory = MAILMAN_HOME user = MAILMAN_UID group = MAILMAN_GID return_path_add delivery_date_add envelope_to_add environment = EXTENSION=${substr_1:$local_part_suffix}:\ RECIPIENT=$local_part$local_part_suffix@$domain In the directors section: list_owner_director: driver = smartuser require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db suffix = "-owner" new_address = "${lc:$local_part}-admin@${domain}" owner_list_director: driver = smartuser require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db prefix = "owner-" new_address = "${lc:$local_part}-admin@${domain}" list_admin_director: driver = smartuser suffix = -admin require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db transport = list_admin_transport list_request_director: driver = smartuser suffix = -request require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db transport = list_request_transport list_director: driver = smartuser require_files = MAILMAN_HOME/lists/${lc:$local_part}/config.db transport = list_transport suffix = +* suffix_optional Pay particular attention to the value of "suffix" in list-director and make sure it agrees with RECIPIENT_DELIMITER in ~list/.tmda/config. You should now be up and running with TMDA integrated as the front face of your Mailman lists. If you want to monitor your TMDA pending queue for your Mailman installation you can periodically run tmda-pending -c ~list/.tmda/config Or just drop the following cronjob in the Mailman user's crontab: * * * * * /usr/bin/tmda-pending -CTb | mail you(a)domain.tld to be emailed regular status updates on new messages in TMDA pending.

I'm attaching the plain text to this followup. ---------------------------------------------------------------------- Comment By: Barry A. Warsaw (bwarsaw) Date: 2002-07-31 18:06 Message: Logged In: YES user_id=12800 Actually, I'm sure the fix is anything /but/ trivial since the semantics and interaction of the MM2.0.x member_posting_only, posters, and moderated attributes is simply too confusing. I'm not sure I got it right the first time, and I'm not even sure that my current thinking on the subject is correct. Here is my current thinking about the steps needed to do an upgrade. I'd love to have someone else sanity check this, but I'll understand if no one does or can. We're not going to "fix" 2.1b2 lists, but this might fix things for lists that are upgraded from 2.0.x to 2.1b3. None of this is tested yet -- or even implemented -- since I need to think on it some more and see if this is correct. Have any comments? Oh yeah. I need to put a nice big warning in the UPGRADING file. # Now convert what we can... Note that the interaction between the # MM2.0.x attributes `moderated', `member_posting_only', and `posters' is # so confusing, it makes my brain really ache. Which is why they go away # in MM2.1. I think the best we can do semantically is the following: # # - If moderated == yes, then any sender who's address is not on the # posters attribute would get held for approval. if the sender was on # the posters list, then we'd defer judgement to a later step # - If member_posting_only == yes, then members could post without holds, # and if there were any addresses added to posters, they could also post # without holds. # - If member_posting_only == no, then what happens depends on the value # of the posters attribute: # o If posters was empty, then anybody can post without their # message being held for approval # o If posters was non-empty, then /only/ those addresses could post # without approval, i.e. members not on posters would have their # messages held for approval. # # How to translate this mess to MM2.1 values? I'm sure I got this wrong # before, but here's how we're going to do it, as of MM2.1b3. # # - We'll control member moderation through their Moderate flag, and # non-member moderation through the generic_nonmember_action, # hold_these_nonmembers, and accept_these_nonmembers. # - If moderated == yes then we need to troll through the addresses on # posters, and any non-members would get added to # accept_these_nonmembers. /Then/ we need to troll through the # membership and any member not on posters would get their Moderate flag # set. Then generic_nonmember_action gets set to 1 (hold) so nonmembers # get moderated, and default_member_moderation will be set to 1 (hold) # so new members will also get held for moderation. We'll stop here. # - We only get to here if moderated == no. # - If member_posting_only == yes, then we'll also set # generic_nonmember_action to 1 and we'll turn off the Moderate flag for # members. Then we troll through the posters attribute and add all # those addresses to accept_these_nonmembers. We'll stop here. # - We only get to here if member_posting_only == no # - If posters is empty, then anybody could post without being held for # approval, so we'll set generic_nonmember_action to 0 (accept), and # we'll turn off the Moderate flag for all members. We'll also turn off # default_member_moderation so new members can post without approval. # We'll stop here. # - We only get here if posters is non-empty. # - This means that /only/ the addresses on posters got to post without # being held for approval. So first, we troll through posters and add # all non-members to accept_these_nonmembers. Then we troll through the # membership and if their address is on posters, we'll clear their # Moderate flag, otherwise we'll set it. We'll turn on # default_member_moderation so new members get moderated. We'll set # generic_nonmember_action to 1 (hold) so all other non-members will get # moderated. And I think we're finally done. # # SIGH. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100103&aid=573071&group_i…

Warsaw (bwarsaw) Date: 2002-07-31 18:06 Message: Logged In: YES user_id=12800 Actually, I'm sure the fix is anything /but/ trivial since the semantics and interaction of the MM2.0.x member_posting_only, posters, and moderated attributes is simply too confusing. I'm not sure I got it right the first time, and I'm not even sure that my current thinking on the subject is correct. Here is my current thinking about the steps needed to do an upgrade. I'd love to have someone else sanity check this, but I'll understand if no one does or can. We're not going to "fix" 2.1b2 lists, but this might fix things for lists that are upgraded from 2.0.x to 2.1b3. None of this is tested yet -- or even implemented -- since I need to think on it some more and see if this is correct. Have any comments? Oh yeah. I need to put a nice big warning in the UPGRADING file. # Now convert what we can... Note that the interaction between the # MM2.0.x attributes `moderated', `member_posting_only', and `posters' is # so confusing, it makes my brain really ache. Which is why they go away # in MM2.1. I think the best we can do semantically is the following: # # - If moderated == yes, then any sender who's address is not on the # posters attribute would get held for approval. if the sender was on # the posters list, then we'd defer judgement to a later step # - If member_posting_only == yes, then members could post without holds, # and if there were any addresses added to posters, they could also post # without holds. # - If member_posting_only == no, then what happens depends on the value # of the posters attribute: # o If posters was empty, then anybody can post without their # message being held for approval # o If posters was non-empty, then /only/ those addresses could post # without approval, i.e. members not on posters would have their # messages held for approval. # # How to translate this mess to MM2.1 values? I'm sure I got this wrong # before, but here's how we're going to do it, as of MM2.1b3. # # - We'll control member moderation through their Moderate flag, and # non-member moderation through the generic_nonmember_action, # hold_these_nonmembers, and accept_these_nonmembers. # - If moderated == yes then we need to troll through the addresses on # posters, and any non-members would get added to # accept_these_nonmembers. /Then/ we need to troll through the # membership and any member not on posters would get their Moderate flag # set. Then generic_nonmember_action gets set to 1 (hold) so nonmembers # get moderated, and default_member_moderation will be set to 1 (hold) # so new members will also get held for moderation. We'll stop here. # - We only get to here if moderated == no. # - If member_posting_only == yes, then we'll also set # generic_nonmember_action to 1 and we'll turn off the Moderate flag for # members. Then we troll through the posters attribute and add all # those addresses to accept_these_nonmembers. We'll stop here. # - We only get to here if member_posting_only == no # - If posters is empty, then anybody could post without being held for # approval, so we'll set generic_nonmember_action to 0 (accept), and # we'll turn off the Moderate flag for all members. We'll also turn off # default_member_moderation so new members can post without approval. # We'll stop here. # - We only get here if posters is non-empty. # - This means that /only/ the addresses on posters got to post without # being held for approval. So first, we troll through posters and add # all non-members to accept_these_nonmembers. Then we troll through the # membership and if their address is on posters, we'll clear their # Moderate flag, otherwise we'll set it. We'll turn on # default_member_moderation so new members get moderated. We'll set # generic_nonmember_action to 1 (hold) so all other non-members will get # moderated. And I think we're finally done. # # SIGH. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100103&aid=573071&group_i…

[ mailman-Bugs-589387 ] can user@host.com = user@abc.host.com?

Bugs item #589387, was opened at 2002-07-31 16:42 You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100103&aid=589387&group_i… Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Paul Marshall (paulmarshll) Assigned to: Nobody/Anonymous (nobody) Summary: can user(a)host.com = user(a)abc.host.com? Initial Comment: I have people who subscribe under user(a)host.com however, their email is identified as user(a)abc.host.com. When Mailman sees this it rejects the post claiming that user(a)abc.host.com isn't subscribed to the list. This problem is very similar to the one listed here: http://mail.python.org/pipermail/mailman-users/2002- July/021343.html I tried the solution that the person suggested, modifying SMART_ADDRESS_MATCH =3D 1 in mm_cfg.py, however this still didn't work. I tried it with it set as: SMART_ADDRESS_MATCH = 1 SMART_ADDRESS_MATCH =3D 1 SMART_ADDRESS_MATCH = 0 Although none of these worked, I am assuming it has to be set to true (1). Anyone have any ideas on why that isn't working or whatelse I may need to do? Thanks.

TMDA in front of mailman-users with no check against thesubscriber list
by J C Lawrence 01 Aug '02

01 Aug '02

Another possible use for TMDA: The rate of FAQ questions on mailman-users is high, damn near the majority of the posts. How about setting up TMDA in front of mailman-users with a confirm request text that explicitly asks, HAVE YOU CHECKED THE FAQ AT <URL>? Repeat posters wouldn't be affected. Then again repeat posters usually don't ask FAQs. -- J C Lawrence ---------(*) Satan, oscillate my metallic sonatas. claw(a)kanga.nu He lived as a devil, eh? http://www.kanga.nu/~claw/ Evil is a name of a foeman, as I live.

Given the effective UID etc problem, I can believe. If I hadn't already known how easy it would be to use Exim I might have given up as well (or hand-patched procmail to do what I wanted ala /etc/procmailrcs). >> I was interested in integrating TMDA in a fashion that also leant >> itself to integrating other useful tools, rather than making such >> further extensions difficult.

Many other services and processes execute in nobody.nogroup as a known-safe near jail. I'm very unwilling to alter my security stance by extending the permission set of nobody.nogroup, especially when all those email addresses are within the risk set. -- J C Lawrence ---------(*) Satan, oscillate my metallic sonatas. claw(a)kanga.nu He lived as a devil, eh? http://www.kanga.nu/~claw/ Evil is a name of a foeman, as I live.
