sync_members script

Hello, Just wanted to ask how you manage the following situation: There is a list of people you keep in an sql database. This database is edited/updated daily. From time to time you want to contact these people, so you export them as a flat file and import into Mailman (for example by using sync_members script). You do the mailing and some addresses are removed from Mailman. When you next time sync members from you sql database with Mailman, the sync_members script will add the previously … [View More]

Attachments and blank messages
by Sciamano April 21, 2008

April 21, 2008

Hello, I'm using Mailman to manage a mailing list, which was previously hosted on yahoogroups. I like it so far, but I'm encountering what I think is a filtering problem. Basically, I don't want any attachments except for text files, nor any HTML messages sent to the list. The list seems to work fine for most of the subscribers, except for two of them, whose messages are creating problems: one who uses his office email account and whose server attaches a disclaimer to the messages, and the … [View More]other who is using an Excite email account, which adds an HTML banner to the bottom of his messages. Depending on how I set the list up, only one of these two members messages get delivered to the entire list correctly. The other one's get delivered as blank messages (althought they show up correctly in the archive). I can't seem to be able to set the filtering properties in order to have both members' messages delivered correctly. More specifically, if I set content filtering this way: ------------begin------------------------- Should Mailman filter the content of list traffic according to the settings below? (Edit filter_content): YES Remove message attachments that have a matching content type. (Details for filter_mime_types): BLANK Remove message attachments that don't have a matching content type. Leave this field blank to skip this filter test. (Details for pass_mime_types): BLANK Remove message attachments that have a matching filename extension. (Edit filter_filename_extensions): exe bat cmd com pif scr vbs cpl zip rar ace bin iso jpg jpeg jpe tif tiff gif bmp Remove message attachments that don't have a matching filename extension. Leave this field blank to skip this filter test. (Edit pass_filename_extensions): BLANK Should Mailman collapse multipart/alternative to its first part content? (Edit collapse_alternatives): YES Should Mailman convert text/html parts to plain text? This conversion happens after MIME attachments have been stripped. (Edit convert_html_to_plaintext): YES Action to take when a message matches the content filtering rules. (Details for filter_action): REJECT --------end-------------- the posts from the member using an Excite account get delivered correctly, but those from the member using his office mail get delivered as three attachments, two of which contain the list's header and footer, and one containing the post. The problem is that not every member receives the three attachments correctly, some only receive an empty attachment. I tried changing the collapse_alternatives setting to: ------------begin------------------------- Should Mailman collapse multipart/alternative to its first part content? (Edit collapse_alternatives): NO --------end-------------- But when the list is set up this way, the posts from the "office member" get delivered correctly, but those from the "Excite member" arrive blank. How can I have both members' posts delivered correctly? Please help, thanks a lot. -- Luca Somazzi Milano, Italia [View Less]

chroot, OpenBSD, Apache, and Mailman
by David Newman April 19, 2008

April 19, 2008

Greetings. Apologies if this has been answered before but I didn't find a direct answer in the archives or FAQ. Is there a howto for installing Mailman from source inside the Apache chroot on OpenBSD? I'm struggling with this, using Mailman 2.1.19, Postfix 2.4.3, and OpenBSD 4.2. There's a list of installation steps pasted below. I suspect a permissions problem. Mailman would not serve up pages when all files were owned by group mailman, so I did 'chgrp -R www /var/www/mailman'. But after … [View More]trying to create a list, the aliases file is mode 660, owned by root:www. This is the error in /var/www/mailman/logs/error that results from trying to create a new list: Apr 18 11:21:00 2008 admin(1925): @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ admin(1925): [----- Mailman Version: 2.1.9 -----] admin(1925): [----- Traceback ------] admin(1925): Traceback (most recent call last): admin(1925): File "/var/www/mailman/scripts/driver", line 101, in run_main admin(1925): main() admin(1925): File "/var/www/mailman/Mailman/Cgi/create.py", line 56, in main admin(1925): process_request(doc, cgidata) admin(1925): File "/var/www/mailman/Mailman/Cgi/create.py", line 238, in proce ss_request admin(1925): sys.modules[modname].create(mlist, cgi=1) admin(1925): File "/var/www/mailman/Mailman/MTA/Postfix.py", line 232, in crea te admin(1925): _update_maps() admin(1925): File "/var/www/mailman/Mailman/MTA/Postfix.py", line 53, in _upda te_maps admin(1925): raise RuntimeError, msg % (acmd, status, errstr) admin(1925): RuntimeError: command failed: /usr/local/sbin/postalias /var/www/mailman/data/aliases (status: 1, Operation not permitted) I've also tried putting postalias inside the chroot jail but the error above persists. Thanks in advance for clues on getting this working. dn PROCEDURE FOR INSTALLING MAILMAN IN OPENBSD 4.2 APACHE CHROOT 1. Read all of the installation manual, or at least up to chapter 6, before proceeding: http://mailman.sourceforge.net/mailman-install/index.html 2. Grab mailman source and unpack: tar xzvf mailman-2.1.19.tgz 3. Add user mailman with UID/GID 91. Run adduser and follow the prompts. Set the shell to nologin and set the password to blank, and then say yes when asked if the user shouldn't be able to log in. 4. Create the /var/www/mailman directory where everything will go, and set permissions and ownership: mkdir /var/www/mailman chgrp mailman /var/www/mailman chmod a+rx,g+ws /var/www/mailman 5. If it's not there already, install python: pkg_add python-2.4.4p4 and create the appropriate symlinks to make this the default: ln -s /usr/local/bin/python2.4 /usr/local/bin/python ln -s /usr/local/bin/pydoc2.4 /usr/local/bin/pydoc Now we need to get python into the chroot. First let's find out what dependencies python has: #ldd /usr/local/bin/python /usr/local/bin/python: Start End Type Open Ref GrpRef Name 00000000 00000000 exe 1 0 0 /usr/local/bin/python 05054000 25096000 rlib 0 1 0 /usr/local/lib/libpython2.4.so.0.0 068bd000 268c1000 rlib 0 1 0 /usr/lib/libutil.so.11.0 05b7c000 25ba2000 rlib 0 1 0 /usr/lib/libstdc++.so.42.0 070f2000 270f9000 rlib 0 1 0 /usr/lib/libm.so.2.3 0b296000 2b29f000 rlib 0 1 0 /usr/lib/libpthread.so.8.0 05d9d000 25dd1000 rlib 0 1 0 /usr/lib/libc.so.41.0 0a739000 0a739000 rtld 0 1 0 /usr/libexec/ld.so OK, so all of these files and directories need to go into the chroot jail: mkdir -p /var/www/usr/lib mkdir -p /var/www/usr/libexec mkdir -p /var/www/usr/local/bin mkdir -p /var/www/usr/local/lib cp /usr/local/bin/python /var/www/usr/local/bin cp /usr/local/lib/libpython2.4.so.0.0 /var/www/usr/local/lib cp /usr/lib/libutil.so.11.0 /var/www/usr/lib cp /usr/lib/libstdc++.so.42.0 /var/www/usr/lib cp /usr/lib/libm.so.2.3 /var/www/usr/lib cp /usr/lib/libpthread.so.8.0 /var/www/usr/lib cp /usr/lib/libc.so.41.0 /var/www/usr/lib cp /usr/libexec/ld.so /var/www/usr/libexec And you'll also need some stuff from /etc in the chroot jail for UIDs and GIDs to work: mkdir -p /var/www/etc/ cp /etc/group /var/www/etc/ cp /etc/localtime /var/www/etc/ cp /etc/login.conf /var/www/etc/ cp /etc/passwd /var/www/etc/ cp /etc/pwd.db /var/www/etc/ mkdir -p /var/www/usr/share cp -R /usr/share/nls /var/www/usr/share 6. If it's not there already (try "cc" from the command line), install the compilers package: tar -C / -xzphf ${RELEASEPATH}/comp42.tar.gz 7. From the directory where you unpacked Mailman, configure and install the Mailman software: ./configure --prefix=/var/www/mailman --with-cgi-gid=67 \ --with-mail-gid=201 make make install Assuming this goes well: make clean 8. Check file permissions /var/www/mailman/bin/check_perms -f Keep repeating this step until there are no errors. 9. (Optional) Make private archives private cd /var/www/mailman/archives chown www private chmod o-x private 10. Now configure the web server to use Mailman. Open /var/www/conf/httpd.conf and add this: ScriptAlias /mailman/ /var/www/mailman/cgi-bin/ Alias /pipermail/ /var/www/mailman/archives/public/ <Directory "/var/www/mailman/archives/public/"> AddDefaultCharset Off </Directory> If you're using VirtualHosts, then the lines above belong inside each VirtualHost directive too, at least for the vhosts using Mailman. And copy the Mailman icons into place: cp /var/www/mailman/icons/*.{jpg,png} /var/www/icons/ Then restart Apache: apachectl graceful 11. Now we set up Postfix to work with Mailman. First, in /etc/postfix/main.cf, the GNUC docs say to change: unknown_local_recipient_reject_code = 550 from its current setting of 450. Also, it says to set: recipient_delimiter = + even though the current setting is: recipient_delimiter = - I'm not making this change for now, and sticking with the '-' setting. 12. Then proceed directly to section 6.1.2 of the docs to set up virtual domains. We'll come back to section 6.1.1 on Postfix-Mailman integration in a few minutes. Specifically you want to add a pointer to the end of the virtual_alias_maps parameter in /etc/postfix/main.cf. For example: virtual_alias_maps = proxy:mysql:/etc/postfix/sql/forwardings.cf proxy:mysql:/etc/postfix/sql/email2email.cf hash:/var/www/mailman/data/virtual-mailman 13. Now put the following at the end of /usr/local/lib/mailman/Mailman/mm_cfg.py, replacing 'domain1.tld' and 'domain2.tld' as appropriate with your domain names: MTA = 'Postfix' MAILMAN_SITE_LIST = 'mailman' DEFAULT_EMAIL_HOST = 'domain1.tld' DEFAULT_URL_HOST = 'domain1.tld' DEFAULT_URL_PATTERN = 'https://%s/mailman/' PUBLIC_ARCHIVE_URL = 'https://%(hostname)s/pipermail/%(listname)s' IMAGE_LOGOS = '/icons/' MTA = 'Postfix' POSTFIX_ALIAS_CMD = '/usr/local/sbin/postalias' POSTFIX_MAP_CMD = '/usr/local/sbin/postmap' POSTFIX_STYLE_VIRTUAL_DOMAINS = ['domain2.tld', 'domain1.tld' ] add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST) add_virtualhost('domain2.tld', 'domain2.tld') 14. Set up a site-wide mailing list called 'mailman'. Mailman MUST see this list to start: /var/www/mailman/bin/newlist mailman Fill out the admin's email address and choose a password. 15. Set up Mailman maintenance as a crontab run by the mailman user: chown -R mailman:mailman /var/www/mailman cd /var/www/mailman/cron crontab -u mailman crontab.in 16. Now start the mailman daemon: /var/www/mailman/bin/mailmanctl start After starting the program the admin named for the 'mailman' list should get an email. 17. To start mailman every time the system starts, add these lines to the end of /etc/rc.local: # Mailman startup if [ -x /var/www/mailman/bin/mailmanctl ]; then echo -n ' mailman' /var/www/mailman/bin/mailmanctl -s -q start fi 18. Create site and list creator passwords. You want to read chapter 12 of the GNU docs carefully; these are like being root within Mailman! /var/www/mailman/bin/mmsitepass /var/www/mailman/bin/mmsitepass -c 19. Add mailman to www group. I don't know if this is a good security practice (I suspect it's a bad idea) but I was unable to get Mailman to work without this step. In /etc/group and /var/www/etc/group: www:*:67:mailman and restart Apache and mailman: apachectl restart /var/www/mailman/bin/mailmanctl restart 20. (Necessary?) Find which postalias stuff needs to go into the chroot jail: ldd /usr/local/sbin/postalias /usr/local/sbin/postalias: Start End Type Open Ref GrpRef Name 00000000 00000000 exe 1 0 0 /usr/local/sbin/postalias 015ad000 215b8000 rlib 0 2 0 /usr/lib/libssl.so.11.0 0a28e000 2a2bd000 rlib 0 2 0 /usr/lib/libcrypto.so.13.0 00eaf000 20ebb000 rlib 0 1 0 /usr/local/lib/libpcre.so.1.1 0688d000 26893000 rlib 0 1 0 /usr/local/lib/libsasl2.so.2.22 03e8c000 23eba000 rlib 0 1 0 /usr/local/lib/libmysqlclient.so.18.0 00a26000 20a5a000 rlib 0 1 0 /usr/lib/libc.so.41.0 08a55000 28a5d000 rlib 0 1 0 /usr/lib/libz.so.4.1 08e39000 28e40000 rlib 0 1 0 /usr/lib/libm.so.2.3 0d23a000 0d23a000 rtld 0 1 0 /usr/libexec/ld.so And copy over the files: mkdir /var/www/usr/local/sbin cp /usr/local/sbin/postalias /var/www/usr/local/sbin/postalias cp /usr/lib/libssl.so.11.0 /var/www/usr/lib/libssl.so.11.0 cp /usr/lib/libcrypto.so.13.0 /var/www/usr/lib/libcrypto.so.13.0 cp /usr/local/lib/libpcre.so.1.1 /var/www/usr/local/lib/libpcre.so.1.1 cp /usr/local/lib/libsasl2.so.2.22 /var/www/usr/local/lib/libsasl2.so.2.22 cp /usr/local/lib/libmysqlclient.so.18.0 /var/www/usr/local/lib/libmysqlclient.so.18.0 cp /usr/lib/libc.so.41.0 /var/www/usr/lib/libc.so.41.0 cp /usr/lib/libz.so.4.1 /var/www/usr/lib/libz.so.4.1 cp /usr/lib/libz.so.4.1 /var/www/usr/lib/libm.so.2.3 cp /usr/libexec/ld.so /var/www/usr/libexec/ld.so [View Less]

question about config_list
by charlie derr April 18, 2008

April 18, 2008

Hi, I'm trying to create a template for semi-automatic list creation, and while 'config_list -o' will dump out a floating point number for bounce_score_threshold correctly, when I try to use this generated config file with 'config_list -i' somehow the floating point value gets truncated (in a very pythonic way -- no rounding up) to an integer (though it still retains the floating point notation). I discovered that I didn't actually need a floating point value there (1.0 was just as good … [View More]

Email response very slow using Mailman and sendmail

Hi, We have internal Mailing List server running Mailman 2.1.9 and SENDMAIL 8.13.8. Whenever someone sent email to particular mailing list (everyone(a)managemant.bu.edu)consisting app 300 users recipients receive it after several hours. E.g see the following Email I sent on Apr14th at 3:19PM that came in at 6:09 PM and some received at 7:09 PM. I don't understand why there is so much delay when sending mail to 300 users mailing list. I clearly see in Outlook headers that the mail is sitting … [View More]

Infinite moderation loop for one list
by Ricardo Ramirez April 18, 2008

April 18, 2008

Hello, I am the owner of several mailman lists and I have set up very stringent moderation filters in an effort to curb spam. The filters work as expected except for one list in particular. The list is owned by itself and me. It is configured to send the owner notice of a pending moderation request immediately. The list itself has never received this notice, however I do. Furthermore, when a message gets flagged for moderation, mailman falls into an infinite loop. It's my understanding … [View More]

Again on HTML emails
by Giulio Troccoli April 17, 2008

April 17, 2008

I need to send HTML email, or better I need to be able to do so. I've read a lot of posts that say how to prevent HTML emails to be sent, but I can't seem to be able to set mailman to accept them. I used to use another system to manage my mailing lists that didn't have any problems with HTML email. My "users" are used to receive HTML emails so it's not a problem that they can't read them. I'm glad I changed the old system to mailman and I will be fine even if I have to send plain text emails. … [View More]
