If this works as expected, all the headers below the subject line should end up in the mail body. I've been tracking this bug for a while, apparently mailman's header parsing chokes when you have a header that contains more than 80 (maybe 100?) characters in a row without a space. This breaks horribly when you run spamassassin, due to headers like: X-Spam-Status: No, hits=2.0 required=7.0 tests=SUBJ_ENDS_IN_Q_MARK,TO_LOCALPART_EQ_REAL,X_NOT_PRESENT,RCVD_IN_VADUL,X_RCVD_IN_DUL_FH version=2.21 But it also breaks because outlook has a bug where Message-IDs listed in the References header aren't always separated by spaces. I'm hoping that Barry or someone else can nail this quicker than I can find out which part of mailman may even be responsible for that (I'm still quite busy hacking on exim and spamassassin for sf.net right now) Marc -- Microsoft is to operating systems & security .... .... what McDonalds is to gourmet cooking Home page: http://marc.merlins.org/ | Finger marc_f(a)merlins.org for PGP key

Contributing code?
by David Gibbs June 3, 2002

June 3, 2002

Folks: How does one go about contributing code? I've made some small changes in my cvs sandbox that I think would be useful for the core code. Do I mail them to someone (Barry?) for consideration, post them here, what? The mods I made are fairly simple ... when the admlogin, options, and private templates are loaded, the cursor is automaticly placed in the first form field on the page. I made similar changes in 2.0.11 and my list owners love it. Thanks! david

So I hacked a tiny bit of javascript to position the cursor in the first form field on the admlogin, options, and private templates.

MimeFilter integration with Mailman
by J C Lawrence June 2, 2002

June 2, 2002

<<Reply-To set to mailman-users(a)python.org>> A while back I noticed that while we'd been happily recommending MimeFilter for stripping unwanted MIME parts from messages before they got to mailman, nobody had bothered to say how to run it beyond "chuck it in the alias file". Problem: those instructions (generally) won't work. Reason: Mimefilter tries to create files and a temp directory in its CWD, and at least under postfix that means /var/spool/postfix which here is root.root/0755 (and I'm not about to change that). So I spent some time this morning and threw something together a little slicker. Its essentially a wrapper around Mailman's wrapper. What I got seems to work. I don't and won't claim beauty. --<cut>-- #!/bin/bash # Syntax: # # mimestrip <action> <target> # # Both arguments will be passed to /var/lib/mailman/mail/wrapper # in the same order, without change. # # All other arguments will be gleefully discarded. # # Author: J C Lawrence <claw(a)kanga.nu> # ACTION=$1 TARGET=$2 export PATH=/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/sbin:/usr/sbin # -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= # Config (Edit this bit to suit your setup!) # -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= # Safe working directory for mimefilter. We need to do this as # postfix by default will execute this script in /var/spool/postfix and # mimefilter will try and create temp directories and files under there. # Note: Make sure that the value of tmpdir is writeable by the UID or GID # that this script will execute under. tmpdir="/tmp/mimestrip.${$}" # Do you want to save an mbox of the messages before filtering # in $savefile_pre? (0/1) save_pre=1 # Do you want to save an mbox of the messages after filtering # in $savefile_post? (0/1) save_post=1 # File to save pre-filtered messages in savefile_pre="/tmp/mimestrip.prefilter" # File to same post filtered messages in savefile_post="/tmp/mimestrip.postfilter" # Send a copy of every processed message to the list maintainer? (Y/N) copy_maintainer="y" # -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= # MimeFilter setup (Don't edit from here down) # -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= # The name of the mailing list this message is intended for. Used # as the return address of the warning issued to the orginal author # if the message is not already clean. export list=${USER} # The address of the mailing list this message is intended for. # Used in the X-Loop field of the warning issued to the original # author if the message is not already clean. export listaddr=${USER}@${DOMAIN} # The administrative (owner) address of the mailing list this # message is inteded for.

The script is Postfix specific in that it expects the $USER and $DOMAIN in its environment to be respectively set to the LHS and RHS of the address the message was sent to. Hack freely for your MTA of choice if it does something different. Why not use demime which does all sorts of cool things like Yahoo signature removal and getting rid of unnecessary quoted-printable? demime strips all MIME parts, which is fine if that's what you want. However there are certain MIME parts that I specifically want to let thru to my lists (eg message/rfc822), and I rather like some of mimefilter's other features thta demime doesn't share like emailing the original poster with a warning that parts were removed from their message. Yeah, those extra messages are annoying to the posters. They're intended to be and I like that. I don't want posters sending unwanted MIME parts to my lists. Note: You can turn off that feature in Mimefilter's config. I also wanted a way to send MIME messages thru to my lists without doing any MIME stripping. A bypass if you would. Typically I'd use this for valid/valuable list messages which contain useful MIME parts (eg an attached image such as a graph diagramming the message content) that would otherwise be stripped my the mimefilter. In the end I did this via a custom X-header: X-MimeStrip: No. Strong suggestion: Configure your lists to hold messages with that header for moderator approval. This will allow you to catch abuse by too-clever posters. Mailman v2.1 largely removes need for this mimestrip filter. If all you want is mimestripping then Mailman 2.1 should be more than enough. However I want more than that. I want mimefilter's annoying messages to posters of unwanted MIME, I want the bypass, I want the ability to save the before and after filtering messages etc, and I really want the ability to ad-hoc extend the filter with other little toys and trinkets as I go along (eg a quoted-printable flattener will likely be next for me here). Adding in something like SpamAssassin into the mail processing pipe with a custom handling rule (eg silently discard messages with high enough scores before passing them thru mimefilter) would be trivially easy and is left as an exercise for the reader. This is barely if at all tested. Caveat Emptor and all that rot. Yeah, I should put this in the FAQ and I hopefully will after I've run it thru a few more exercises here. Enjoy. -- 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.

2.1b4 bug or my problem?
by Luigi Rosa June 2, 2002

June 2, 2002

I just installed 2.1b4 on a fresh Linux installation. Everything is working well except for the URL in the headers and in the web pages. The hostname of the Linux box is mail.hypertrek.info and this is a part of mm_cfg.py: DEFAULT_EMAIL_HOST = 'mail.hypertrek.info' DEFAULT_URL_HOST = 'mail.hypertrek.info' DEFAULT_URL_PATTERN = 'http://%s/mailman/' add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST) DEFAULT_HOST_NAME = DEFAULT_EMAIL_HOST DEFAULT_URL = DEFAULT_URL_PATTERN % DEFAULT_URL_HOST HOME_PAGE = 'index.html' MAILMAN_SITE_LIST = 'mailman' With this settings, the header of the messages of each list and the mailto URL of the web pages are http://mail/mailman.... With the withlist inbterface I tried to change the web_page_url parameter of each list from 'mail' to 'http://mail.hypertrek.info' and the mailto url werw ok, but the headers of the messages and the URL of teh web pages were http://mail.hypertrek.info/... without mailman The question is: can I set the web_page_url variable to 'http://mail.hypertrek.info/mailman/' or there is another solution for this issue? Thanks. Ciao, luigi
