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.

Newbie User
by David Elliott 17 Mar '22

17 Mar '22

Hi, I am a newbie to Mailman and cpanel and I need some help, please. I have set up a mailing list for my tennis club (about 300 on list) and it seems to work ok BUT each recipient only sees the mailing list name rather than his own email name in the 'to' box. One of the recipients recently did a 'reply to all' and consequently sent his reply to the whole mailing list. I'm sure there must be a way to prevent this but I can't find it! David Elliott

Add "sender's name/email" to BODY of mail as header?
by Mal 16 Feb '21

16 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 09 Sep '20

09 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

Spam Subscriptions
by David Andrews 04 Jun '18

04 Jun '18

I have a mailman installation with over 300 lists. It is cPanel, but I am the administrator so have access to command line etc. I have just two lists that receive a bunch of spam subscribes each day -- hundreds of them, in fact. For some reason -- which is good, they are held, so don't go through, not quite sure why. Two questions -- first is there a file I can erase for each list that will get rid of all the held subscriptions, without breaking anything else. I tried once, and my installation broke -- don't know if it is related, but don't want to try again unless I do it right. Secondly, there is some commonality in the subscribe addresses, are there strings I can use to discard the subscribes so I never have to see them. Below are examples, there is a common word, or a common word, a period ., and another common word, then a plus sign + then a 4 5 or 6 character word, all alpha, and @gmail.com Here are examples: dragonommz+ jwmidnight+ nommz.naidoo+ If I could knock these out, it would be helpful. This has happened several times previously, but has always stopped after a few weeks. This time it has been a couple months. Finally, I know it is probably too late in the Mailman2 cycle to get a new feature, but in the web UI, it would be nice if you could delete all deferred subscriptions. You can do so with deferred messages, that are held, but not subscriptions. Thanks! Dave

(relatively) new DMARC issues - and Gmail
by Lindsay Haisley 02 Apr '18

02 Apr '18

I've been working with a From-rewriting tool with code taken from Mailman (thanks, Mark!) and discovered a couple of things which I thought deserved posting about. I expect that they peripherally affect Mailman, too. At some point Amazon (amazon.com) started publishing a DMARC "p=quarantine" policy, which means that any email which gets redirected and hits my dmarc_shield piece is going to have its From address re- written to "postmaster(a)fmp.com" (fmp.com has a proper SPF record). I don't know what Gmail's policy is with regard to "p=quarantine" - whether it rejects such email outright or relegates it to the recipient's spam folder. I know that if the sending site publishes "p=reject", redirected email is refused by Gmail at the front door. I'll have to test the "p=quarantine" behavior. Here's the really annoying thing. My dmarc_shield processor rewrites the From header as per SOP for Mailman with the proper switch turned on. The From header address becomes "postmaster(a)fmp.com" with the original From address in the address comment (from xxx at yyz.com). If the email didn't already have a Reply-To address, the original From address is inserted as the Reply-To address. If a Gmail user replies to such an email, the reply goes to the Reply-To address, but Gmail **whitelists** the From address! Thereafter, any email which comes in with a munged From address is accepted, bypassing Gmail's otherwise pretty good spam filtering. I'm noticing a lot of spam email going out with From addresses for which a DMARC "p=reject" policy is published, which means that any such spam redirected to the Gmail user via FMP is also whitelisted. Bah! It's a fucking war zone out there! The only possible solution here would be to randomize the username portion of the rewritten From address, which makes the email look more like spam, and the Gmail user would end up with a whole lot of useless whitelisted address which would need to be deleted. Not to mention the fact that FMP's mail server might be blocked from sending ANY email to Gmail. -- Lindsay Haisley | "The first casualty when FMP Computer Services | war comes is truth." 512-259-1190 | http://www.fmp.com | -- Hiram W Johnson

Only one list not working
by Javier 28 Mar '18

28 Mar '18

¡Hello to everyone! Only one of my lists does not work, the web interface of this list does. When I send an email the list after a while I receive a message with the rejected connection. In the Postfix log I don't see any errors and the telnet connection works. I don't see any errors in Mailman's logs either, but they are strangely empty. Can you think of what the mistake might be? Thank you in advance. Greetings.
