Using cronjob to remove and add members to a mailing list
by Jerry Barnabee 10 Aug '22

10 Aug '22

I want to be able to run a cronjob on my server that uses a php script to add new users and/or remove users from a mailing list. Not having any luck finding any simple examples. My thought is that the php script would get email addresses from a database (which I can do) and then feed them to a mailman command line to either add or remove a user. The cronjob is entered via Cpanel. Have several cronjobs that modify databases but have never tried something that would actually execute a unix command. Thanks, Pineyscripter

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 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 discard expressions
by Jim Dory 08 Mar '18

08 Mar '18

Apparently our host provider performs spam tests only on outgoing, rather than incoming - since my spamassassin blacklists don't have any effect. So I've discovered the filters offered in Mailman after being completely buried by spammers trying to post to our subscriber only list. I've started putting these in Sender Filters: ^[^@]+@bcira\.com$ ^[^@]+@airablo\.com$ ^[^@]+@bfklaw\.com$ ^[^@]+@bettella\.com$ ^[^@]+@areallycool\.com$ ^[^@]+@aristo-tec\.com$ ^[^@]+@benallgood\.com$ ^[^@]+@al-meshkah\.com$ ^[^@]+@atoccs\.stream$ ^[^@]+@authors\.com$ ^[^@]+@aulson\.com$ ^[^@]+@atmyx\.bid$ ^[^@]+@airtecperforms\.com$ but what is the syntax for blocking domains ending in .loan .stream .trade etc, other than .com. I've been reading up on python expressions but at first reading it is a bit overwhelming - hoping for a simple example. I've also started adding in words under Spam filters such as: ^Subject: .*Phentermine ^Subject: .*F\*buddy ^Subject: .*H00kup ^Subject: .*InstaF\*ck ^Subject: .*Instacheat Wondering if anyone would care to share their lists of filters - or a good resource? thanks, Jim

Re: [Mailman-Users] "Bounce action notification" emails for subscribes/unsubscribes
by Terry . 01 Nov '17

01 Nov '17

Hi Mark & others, Sorry for the delay in responding, and thanks for your generous offer of working with my webhost and/or cPanel to solve this. I passed that offer to my webhost, but it seems they have been able to sort it out with cPanel themselves. Here is the response from my webhost: ========================================== The issue with @mydomain.com was caused due to the setting "Discard the email while your server processes it at SMTP time with an error message" under cPanel>>Email>>Default Address. We've setup "Forward to Email Address" to catchall(a)mydomain.com<mailto:catchall@mydomain.com>. As cPanel support explained, this indicates that all mail that is delivered, but does not have an address (like mailman-bounces@) on this server will be delivered to the default account - this can potentially pose the risk of the email account receiving email for accounts that do not exist, something commonly seen when a domain is being spoofed. Otherwise, it will be rejected with "No such user here". ========================================== They then provided some evidence from a log that the problem was fixed. I then tested lists in all 7 domains, and they all sent subscribe/unsubscribe emails to me perfectly. I then asked Jim Dory (who has participated in this thread) to setup a default address for his list, and it worked for him, too. I’m confused by the wording of the above paragraph from the webhost, but maybe they mean that the server is configured to not allow emails to be sent out *from* addresses which can’t receive emails, and this is to help reduce outbound spam. (For years I’ve known that the webhost was fighting outbound spam by preventing email from being sent out from *domains* which I don’t have on that server, but maybe this even applies to the address level.) So, I guess when Mailman tries to send a subscribe/unsubscribe notification email out from mailman-bounces(a)mydomain.com<mailto:mailman-bounces@mydomain.com> to the list owner address, maybe the server blocks it, since that mailman-bounces(a)mydomain.com<mailto:mailman-bounces@mydomain.com> address doesn’t exist, as such. I tested this theory using a less overkill approach, by not using the "catchall" default address method, but just creating a forwarder (alias) for the address mailman-bounces(a)mydomain.com<mailto:mailman-bounces@mydomain.com> which redirects its mail to one of my mailboxes (even to my catchall mailbox), and that seemed to work! I don't think this is to provide an address which will receive emails resulting from subscribes/unsubscribes (since I don't think that process sends anything *to* the mailman-bounces@... address), but just to satisfy the anti-spam requirements of the system that every sending address should be able to receive email, not just bounce it. Any thoughts on this, Mark/others? Confused? I can only imagine that the problems started recently due to some update to cPanel or other change by the webhost, because having looked through the history of my subscribe/unsubscribe email notifications, it looks as if the problems only started a few months ago, but I don’t think I’ve made relevant changes to those domains for years. (When I asked the webhost about this, they responded "Unfortunately, we cannot be sure about this. The cPanel representatives haven't mentioned about any recent changes to the Exim configuration.") Anyway, here is a summary of my subscribe/unsubscribe notification problems that seem to have been resolved by setting the default addresses for my domains to my catchall address, instead of bouncing emails sent to non-existent addresses: 1. For some of my domains/lists I’d receive notifications as *attachments* to emails which have the subject “Bounce action notification” (as per my 1st post). 2. For some of my domains/lists I’d receive subscribe emails as *attachments*, but not receive anything for unsubscribes. (Might be the other way round sometimes.) 3. For some of my domains/lists I’d receive no subscribe or unsubscribe emails at all (as per my 3rd post). Thanks. Terry
