Hi, i`m trying to reject messages bigger then MAX_MESSAGE_SIZE. I configured my Hold.py was described bellow: replaced hold_for_approval(mlist, msg, msgdata, _ MessageTooBig(bodylen,_mlist.max_message_size)) with rej = MessageTooBig(bodylen, mlist.max_message_size) _ raise Errors.RejectMessage, rej.reason_notice_ The message was rejected, but the sender dont receive any notify about that. The mailman vette log too. How can i solve this? Thanks, André Dennis Putnam wrote: > >I am getting back to this and I have a question about maintenance. What >is the correct way to modify this so that it will not get destroyed by >updates? There are two ways to proceed. You can modify Mailman/Handlers/Hold.py itself, but before overwriting it, make a "diff -u" between the base Hold.py and your modified version to use as a patch to apply after any upgrade. A better way is to leave Hold.py unchanged and make your own edited version as say Mailman/Handlers/MyHold.py. Then you can replace the base Hold.py Module with your MyHold.py by putting GLOBAL_PIPELINE[GLOBAL_PIPELINE.index('Hold')] = 'MyHold' in mm_cfg.py. Note that if you are going to do this, and you want also to move MimeDel before Hold, you must either put the above line after the lines GLOBAL_PIPELINE.remove('MimeDel') GLOBAL_PIPELINE.insert(GLOBAL_PIPELINE.index('Hold'), 'MimeDel') in mm_cfg.py or put it before, but then also change GLOBAL_PIPELINE.insert(GLOBAL_PIPELINE.index('Hold'), 'MimeDel') to GLOBAL_PIPELINE.insert(GLOBAL_PIPELINE.index('MyHold'), 'MimeDel') I recommend the former as in # # Put MimeDel ahead of Hold so "too big" is based on content filtered # message. # GLOBAL_PIPELINE.remove('MimeDel') GLOBAL_PIPELINE.insert(GLOBAL_PIPELINE.index('Hold'), 'MimeDel') # # Replace Hold with local version # GLOBAL_PIPELINE[GLOBAL_PIPELINE.index('Hold')] = 'MyHold' Since mm_cfg.py survives upgrades, this should survive. >Also does this same procedure apply to other automatic rejections such >as implicit destination? >On 9/24/2012 8:43 PM, Mark Sapiro wrote: >> >> To automatically reject or discard messages that exceed the list's size >> limit, find the section of the Mailman/Handlers/Hold.py that ends with >> the lines >> >> >> if bodylen/1024.0 > mlist.max_message_size: >> hold_for_approval(mlist, msg, msgdata, >> MessageTooBig(bodylen, >> mlist.max_message_size)) >> # no return >> >> (there is one wrapped line in the above) and replace >> >> hold_for_approval(mlist, msg, msgdata, >> MessageTooBig(bodylen, >> mlist.max_message_size)) >> >> with >> >> rej = MessageTooBig(bodylen, mlist.max_message_size)) >> raise Errors.RejectMessage, rej.reason_notice >> >> to reject the message or with >> >> raise Errors.DiscardMessage >> >> to discard the message.

Add "sender's name/email" to BODY of mail as header?
by Mal 17 Feb '21

17 Feb '21

I want all mails sent to the list to come from the list's email address... But, in this case, if the user forgets to sign their name at the bottom of their mail body, effectively the mail to the list is anonymous...! Is there a way to add the user name (or email address) to the top of each mail so that the mails have the name of the sender, while the mail itself comes from the list address? I have looked high and low for an answer, but noone seems to have the solution. Thank you! Mal

Mailman CGI Error-Group mismatch error
by Wang, Mary Y 10 Sep '20

10 Sep '20

Hi, I received the following error this morning. So I rerun configure again with the following command: ./configure --with-cgi-id=apache --prefix=/var/mailman. I'm still getting the same error. Is there any place that I can look for so that I can debug this problem better? Perhaps, looking at the config history file or something. Any other places that I can check the cause of this error? "Mailman CGI error!!! The Mailman CGI wrapper encountered a fatal error. This entry is being stored in your syslog: Group mismatch error. Mailman expected the CGI wrapper script to be executed as group "nobody", but the system's web server executed the CGI script as group "apache". Try tweaking the web server to run the script as group "nobody", or re-run configure, providing the command line option `--with-cgi-gid=apache'." Thanks Mary

Find a smtp server to send out emails
by Leon 20 Mar '20

20 Mar '20

Hi, This problem is not caused by mailman, but I still want to give it a shot here. I'm hosting a mailing list on top of mailman. Emails are supposed to be sent out by AWS ses. However, ses requires that sender address must be verified, which leads to a problem that emails sent by subscribers to mailing list cannot be sent to other subcirbers, since their addresses are not verified. And it is impossible to verified every subscriber. Are there smtp service providers allowing unverified email address to send out emails, or do I have other solutions? Thanks. Leon

Debugging mass invitations using web page interface...
by The Mailing List Server Admin 05 Sep '19

05 Sep '19

Dear Mailman Cognoscenti, I'm helping one of my list owners send out 5K plus invitations to students to subscribe to his mailing list. Our current configuration: Mailman v2.1.20 RHEL v5.11 Semdmail v8.13.8 Apache v2.2.3 Since this was the first time doing this, I suggested breaking the batch input into 3 groups, 50, 500, and the rest. The 50 went fine, as did the 500, but the largest batch gave him a generic web server error: > Internal Server Error > > The server encountered an internal error or misconfiguration and was > unable to complete your request. > > Please contact the server administrator, root(a)conundrum.unh.edu and > inform them of the time the error occurred, and anything you might > have done that may have caused the error. > > More information about this error may be available in the server > error log. I looked at the logs and I couldn't find anything that hinted at what went wrong. So I asked the owner to send me the last back and I'd give it a try. I wrote a script that removed folks already subscribed to his list and split the remaining subscribers up into 6 files with a thousand records each. I just tried uploading the 1st batch of 1K, with the following options: Subscribe these users now... (*) Invite Send welcome message... (*) No Send notifications... (*) No And entered a 7 line paragraph explaining the invitation. I ended up having the same error happen. Looking at the Mailman logs, I can't see any difference before or after my submission. In the HTTPD logs, I see: >> [Fri Aug 26 19:59:23 2016] [warn] [client 132.177.215.132] Timeout >> waiting for output from CGI script >> /usr/local/mailman/cgi-bin/admin, referer: >> https://lists.unh.edu/mailman/admin/campus.connection/members/add >> [Fri Aug 26 19:59:23 2016] [error] [client 132.177.215.132] >> Premature end of script headers: admin, referer: >> https://lists.unh.edu/mailman/admin/campus.connection/members/add So is there an inherent limit to the number of invites that can be submitted via the web form? As a work around, how would I do large invites on behalf of the owner from the command line, including the 'extra text' that is allowed via the web interface? -- Cordially, the UNH Mailing List Server Admins Bill Costa, senior admin (603) 862-3056

changing domains on Mailman implementation
by Keith Seyffarth 20 Sep '18

20 Sep '18

Is there an efficient way to change the domain name that mailman is affiliated with? I have two mailing lists that were created for an organization before that organization had their own domain. At the time the organization was sure they did not want their own domain and would not be getting a domain. Since then, they have chosen to get a domain and set up a web site. I would like to move their mailing lists onto their domain. It looks like the process for this is: 1) get the list of subscribers 2) delete the mailing list from the one domain (losing the archives) 3) create the mailing list on the new domain 4) subscribe the list of subscribers This process doesn't seem too difficult, but I would prefer to keep the archives, if possible. Both domains are on the same server, running CentOS7 and PLESK 12.5, if that makes a difference. Thanks, Keith

Mailman 2.1.23 install on Ubuntu Desktop 16.04
by Caesar Samsi 31 Dec '16

31 Dec '16

Hi all, Mark, Barry, Ive finally formalized my cookbook to install mailman. The base installation is a mail server (the usual suspects: postfix and dovecot) that hosts multiple domains (virtual domains). I wanted the flexibility of virtual domains so I can consolidate mail server hosting for several domains that I have. The cookbook can be found here: https://caesarsamsi.wordpress.com/2016/12/31/install-a-lamp-server-and-mail… due to its file size (about 140KB) which can’t be attached to this mailing list email. You could probably use the insights from the cookbook to install mailman on a simple one domain mail server. Let me know if clarification is needed and typos or errors found. Cheers, I hope you enjoy the journey! Caesar.

After migrating list to new server, config.pck database gets truncated by web UI
by Jay Sekora 29 Dec '16

29 Dec '16

(Note PS at bottom!) Hi. I'm prepping to migrate a bunch of lists (one at a time, due to huge number of lists and huge size of archives) from one server to another, and I've hit a snag with the first list I'm trying. After migrating the list (as described below), I can go to the lists admindb page on the new server and get the list of pending requests that was on the old server, but immediately the request database gets truncated. (It stays a valid pickle file, it just gets all the requests emptied out of it, so the file itself is much shorter but non-zero length.) This happens *when I load* the admindb page, not when I submit the form. That seems really weird to me, since I'd expect a page load would only read the pickle, not write it. The old server is running Debian and Mailman 2.1.13 (from the Debian package). The new server is running Ubuntu and Mailman 2.1.16 (from the Ubuntu Trusty package; we need to run Trusty for now for complex and uninteresting reasons; I'd rather run 2.1.18, and may look into running that on Trusty once I get the basic migration issues resolved). Relevant UIDs and GIDs (www-data:www-data and list:list) are the same on both systems. Short version: I rsync -aSHov /var/lib/mailman/lists/$listname/ new-server:/var/lib/mailman/lists/$listname and similarly copy the public and private archives (preserving symlinks as needed). check_perms on both systems reveals similar errors which look cosmetic (things like rotated logs, temporary directories where I've copied things, and the like), but I haven't yet let it run to completion because of the volume of our archives. Then I change host_name via the web interface and m.web_page_url interactively with withlist (using fix_url seems not to work when changing http: to https:) and m.Save(). One *possibly* relevant detail is that the new host doesn't currently have a valid certificate. (It's using the old host's cert, and I manually allow the exception in my web browser for testing.) But for Mailman 2, the only http{,s} traffic should be sent from my browser, right? This kind of has the feel of a permissions problem, but clearly the CGI scripts can read from and write to the request.pck database. (And changes to the list config data in config.pck seem to be working normally.) As I said, check_perms hasn't run to completion yet because it's plowing through the (already pre-rsync'ed) archives, but it got through the things in /var/lib/mailman/lists and didn't find anything wrong with this list. There's nothing interesting in the Mailman logs (which Debian/Ubuntu put in /var/log/mailman), and the only thing in the Apache error logs is a warning that the cert it has configured doesn't match its hostname. Anybody have any ideas? Jay PS -- I composed this all last night. Today, the behavior has changed: This morning, a new message was received by the list (forwarded from the old list server to the new list server, and added to request.pck on the new server by the new Mailman installation). Now, when I load the admindb page, the old requests (which were in the request.pck copied from the old server) are all immediately thrown away (although displayed in the admindb form) but the new request which came in this morning remains. So it kind of looks like something about the old requests causes the list to think they're invalid and discard them when it loads them. I initially saw this behavior with "require_explicit_destination" on and "acceptable_aliases" empty, but turning off "require_explicit_destination" and putting just the local part of the list address in "acceptable_aliases" doesn't make any difference. -- Jay Sekora Linux system administrator and postmaster, The Infrastructure Group MIT Computer Science and Artificial Intelligence Laboratory

Mailman Hosting
by Odhiambo Washington 24 Dec '16

24 Dec '16

Hi, Does anyone know of a provider who hosts Mailman and who has a good reputation with American ISPs - Verizon and ATT, etc? These providers somehow have notoriety blocking mailing list emails. I'm currently hosting with a provider based in Oz, but having some difficulties when it comes to Verizon and ATT. AOL, Gmail, Hotmail, Outlook, Yahoo etc are all accepting mails, but majority of the subscribers are with Verizon/ATT and that has really affected one list that I have so I need to change. Please recommend one. -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254 7 3200 0004/+254 7 2274 3223 "Oh, the cruft."
