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.

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 18 Mar '22

18 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 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

Very strange issue With Mailman + Exchange(?)
by Bruce Johnson 30 Jul '20

30 Jul '20

I am not sure how to figure this out. Lengthy explanation: Internally in our Exchange server, that address is a distribution group whose only member is the actual <list-name>@lists.pharmacy.arizona.edu, because the Mailman server is not our mail server. (we have a mildly complicated setup: hybrid OnPrem and O365 exchange + Barracuda spam appliance in front of all of it, which is our actual SMTP server. Outgoing email from the list server bypasses Exchange and is sent directly to the Barracuda SMTP server. For two users and ONLY these two users, somewhere between them and mailman and back, the Mailman list is being expanded to put all the members of the list on the CC line. It then gets held for approval with a ’too many addresses’ message. I have watched them send an email to the affected list; the list address is NOT in their local address cache, and they are NOT entering any other addresses in the email other than the list address. The only address that appears on the email in their Sent folder is the list address. Other users in our organization can send to these same lists without this happening. In fact one of the affected users can send to *other* lists on our server with no problems. These are two different lists. I don’t know that this is specifically a Mailman problem (because it’s only happening with specific users) but I cannot see how list members are getting stuffed on the CC line otherwise; because Exchange only knows the list address, not the members; only Mailman does. TLDR: Somehow the all the list addresses are getting stuck onto the list message which then holds it for approval for ’too many addresses’. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs

What is character set of the log files?
by Brett Delmage 02 Jun '20

Hi! What is the character set coding for the log files, please? I'm using MM 2.1.29 I'm asking because a list admin want to view them via a web browser and I need to config Apache. Thanks. Brett

Mailman3 list migration possibly new domain
by Andrew Hodgson 31 May '20

31 May '20

Hi, I have a list to migrate to Mailman3 from Mailman2 but the domain of the list may change at some point in the future. I was hoping to marry up the 2 events but its not looking likely at the moment. From what I have tested the Hyperkitty archives can be imported into any list so long as it exists. My question relates to importing the Mailman configuration files. If we take a Mailman configuration file for list(a)domain1.com<mailto:list@domain1.com>, if I import that into a new Mailman3 list list(a)domain2.com<mailto:list@domain2.com> will it cause a problem? Taking that a step further could we import list(a)domain1.com<mailto:list@domain1.com> into list2(a)domain2.com<mailto:list2@domain2.com>? I am aware I could just export the users and re-import into a new list if all else fails. Suggestions welcome. Thanks. Andrew.

Re: Differences between Mailman 2 and 3
by Iain Harrison 30 May '20

30 May '20

The biggest difference for me is that Mailman 2 was a swine to install and get working, but it was eventually possible. In comparison with that, Mailman 3 has proved completely impossible. It's not as if I'm trying to install on anything obscure: it's a very standard Debian Buster setup running Exim4. I don't understand what the problem is, but following instructions I can find anywhere on the web leave me with a setup that simply doesn't work. With Debian, it should be a simple matter of "sudo apt-get install packagename" but that certainly isn't the case for Mailman! Now I'm looking for an alternative way to run mailing lists. Can anyone suggest either a good alternative, or a way to get Mailman 3 to install? -- Iain

DNSException: No Nameservers available for ...
by Lars Bjørndal 29 May '20

29 May '20

Hello One member of a mailman mailing list on my system receives an error message when posting to the list: You are not allowed to post to this mailing list From: a domain which publishes a DMARC policy of reject or quarantine, and your message has been automatically rejected. If you think that your messages are being rejected in error, contact the mailing list owner at nssf-styre-owner(a)nssf.us. In /var/log/mailman/error, I have: DNSException: No Nameservers available for username(a)blindeforbundet.no (_dmarc.blindeforbundet.no) There are not published any DMARC policy for the domain. I'm running mailman-2.1.30-1.fc31.x86_64 on a Fedora 31 server. I hope someone on tis list can help me figure out what's going on, and hopefully a fix. Thanks in advance Lars
