To use or not to use content filtering
by Andrew Hodgson Jan. 27, 2011

Jan. 27, 2011

Hi, I have read various discussions on this list about content filtering settings in Mailman. For the most part, I usually leave content filtering on, and leave the defaults, primarily for protecting list users against malicious attachments (I am enough of an MS veteran now not to care about filtering all HTML). However, over recent months we have had some issues with content filtering on some lists, with users who send emails with disclaimers, where the disclaimer is added as an attachment to the message, and Mailman appears to strip off the actual message, leaving the disclaimer to post to the list, and of course adding in the standard footer. Are people using content filtering in lists where most people are using MS products, and a suitable antivirus package on the MTA as well as a low posting size limit, or are there any tweaks I can make to the content filtering settings that may get some of this stuff through? Thanks. Andrew.

postfix-to-mailman.py => mail loops back to myself
by Russell L. Carter Jan. 27, 2011

Jan. 27, 2011

Hi there, I've spent the afternoon attempting to install mailman on debian testing with postfix, following the instructions in /etc/mailman/postfix-to-mailman.py precisely, and I'm getting the classic 'mail for "host" loops back to myself'. From my getting to know the issue sessions with google there appear to be a variety of ways this can show up. Anyway I've checked permissions, am able to create lists and add users with confirmation, etc. But sending from the user to the list bounces with postfix complaining 'loops back to myself'. Q1: I was not previously using postfix virtual domains as described in www.postfix.org/VIRTUAL_README.html, should I be? If so I'll go off and try to figure out how the information in there is related to the instructions in /etc/mailman/postfix-to-mailman.py. However, AFAICT, the two sources appear to have zero intersection even though the concepts are of course are quite similar. If the answer to Q1 is "no", the only change to my existing system was to add a CNAME 'lists.pinyon.org' pointing to 'quine.pinyon.org'. Here is the relevant part of of my long time working main.cf, with the mailman modifications (all checked, many times): ------------------------------------------------------------------ myhostname = quine.pinyon.org mydomain = pinyon.org myorigin = $mydomain mydestination = $myhostname, localhost.$mydomain, $mydomain, mail.$mydomain, www.$mydomain, ftp.$mydomain troupesalamat.com masquerade_domains = pinyon.org relay_domains = lists.pinyon.org $mydestination esturion.net troupesalamat.com relay_recipient_maps = hash:/var/lib/mailman/data/virtual-mailman transport_maps = hash:/etc/postfix/transport mailman_destination_recipient_limit = 1 ------------------------------------------------------------------ I've tried quite a few permutations of ordering, etc., but no luck. Q2: Any idea what might be the problem? Many thanks! Russell

image filtering
by Troy Knabe Jan. 27, 2011

Jan. 27, 2011

A user just sent a message to a list, and the inline image was removed. Under "Content filtering" I have "Should Mailman filter the content of list traffic according to the settings below?" and No is checked. Where else should I be looking? Thanks -Troy

The locks log shows one broken expired lock, possibly due to your frequent reboots. The error log shows only unparseable messages but there are over 3000 of them in about 26 hours. Correlation with the qrunner log shows these are all processed by BounceRunner. Thus they are unparseable messages sent to the LIST-bounces addresses. Normally, unparseable messages are spam, but possible they are real bounces from some broken MTA. The next time you have an accumulation of /var/spool/mailman/bounce/*.pck files, examine some of them with Mailman's bin/dumpdb or bin/show_qfiles tool. If they look like legitimate bounce messages, they may give you some information about your bounces, but note that the particular messages that are unparseable do not get scored for any user. If they look like spam, then your problem may just be massive amounts of spam sent to your LIST-bounces addresses. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

Solaris 10 and Python
by McNutt Jr, William R Jan. 24, 2011

Jan. 24, 2011

Has anyone successfully made this work on a Sun Solaris 10? I've been at this for three days and no matter what I do, I only manage to change error messages. At this point I've made it through the ./configure step, but it's breaking on make install. It's a Sun Fire x4100 running solaris 10. I've got mailman 2.1.14 and python 2.6.2 If you've made it work under that configuration and are willing so show off your 'leet skills helping me deal with this, please shoot me a note at mcnutt(a)utk.edu<mailto:mcnutt@utk.edu>.

List Membership Change
by McNutt Jr, William R Jan. 24, 2011

Jan. 24, 2011

I'm still cleaning up after my hardware failure, and I've got a list admin who is complaining about his membership list. Now - what I did was just copy the /lists/* from the old server to the new one and run ./withlist -l -r fix_url LIST_NAME -u new-domain.example.org And bin/arch mylist archives/private/mylist.mbox/mylist.mbox for each list. The complaint follows: "We went from 340 members to 465 in one list and from 102 to 59 in the other." Is there anything else I can do?

Re: [Mailman-Users] private lists with real name signatures
by Doug Gaff Jan. 24, 2011

Jan. 24, 2011

(Sorry to resurrect an old thread, but I recently switched to a VPS, and now finally have access to the mailman install.) As mentioned in the old thread, I'd like add %(member_name) and %(member_address) as variables that can be used in the msg_header and msg_footer fields if desired by the list administrator. The idea is that messages sent to an anonymous mailing list could have msg_header set to this: %(member_name) writes: And in the subscription list, member_name would be the "handle" used by each person. This way, the email addresses stay anonymous, but the messages are still signed. Consider it "semi-anonymous". :) I'm not totally getting the custom handler thing, and I need this only for one of the lists I host. Something the list admin could setup if desired. It seems like a handler would fire for everyone. A better solution, if a hack, would be to modify the mailman source code, but I could use some pointers on where to get started.

Seems like that would be easier. It's not available because it's not available. Yours is an unusual use case; "normally" the poster's name is available in the From field, or not at all. No malice in this<wink>, it just never occurred to anybody to make it available for message headers and footers. This Handler could be added to a future version of Mailman, but 2.x is not planned for further development, and 3.0 is still some months away. No reason for you to wait!

owner alias bounces
by Florian Effenberger Jan. 23, 2011

Jan. 23, 2011

Hello, on all my mailing lists, I have the problem that mails to the -owner alias seem to bounce. The sender doesn't receive a bounce, but the list owners don't receive the e-mail -- instead, failures are logged in mailman's bounce log. The owners are the same as the subscribers (it's an internal list), and mails to the list reach these destinations itself, so it can't be a general problem. The receipients are within and outside of our domain. I'm a bit clueless and can't find much in the logs. Any idea where to start searching? Thanks, Florian

Re: [Mailman-Users] control mail distribution ..
by Khalil Abbas Jan. 23, 2011

Jan. 23, 2011

well, attached are parts of the error and qrunner logs.. I also forgot to mention that I also delete the following files: rm /var/lib/mailman/data/*.pck -f rm /var/lock/mailman/*.* -f the first one also eats up my little space on the hard drive, and the other locks the lists n they can’t send.. what I need to know, why the subscribers are being removed? is it because of misconfiguration of mailman? or because of outside MTA’s like yahoo and hotmail rejecting mail from my servers because I need to control the flow of messages going out from my servers? another thing worth to mention, the servers are not blocked by hotmail because I sent single test messages from all my servers to some of my subscribers that were removed from my lists and they received them with no problems..

You're the one with the logs and other evidence that might enable someone to answer this. >and I understand the conclusion to my previously asked question, >deleting these files does not get the subscribers to be removed right? Right. Deleting *.pck files from /var/spool/mailman/bounce will result in those specific bounce messages (each file is one queued bounce message) being lost and therefore not processed. Likewise, deleting bounce-events-*.pck files from /var/lib/mailman/data/ will in the case of active files result in the bounce information in the file being unprocessed, and in the case of "dead" files have no effect because whatever residual bounce info is in those files is lost. In any event, removing these files will result only in bounce scores not being incremented and subscribers not being removed, not the reverse. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
