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

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

DMARC hack
by Allan Hansen 10 Apr '16

10 Apr '16

Hi, I have waited almost a year for AOL and Yahoo to admit that they messed up and to remove their DMARC policy. My AOL and Yahoo subscribers are pretty upset at me because I won’t let them post. A number now have two subscriptions, one for posting (from GMail) and another for receiving the messages. So against my better judgement, I included this hack in Cleanse.py; 22c22 < from email.Utils import formataddr, parseaddr — >from email.Utils import formataddr 69,74d68 < < # Added to deal with DMARC issuej < name, addrs = parseaddr(msg.get('from')) < addrs += '.invalid' < del msg['from'] < msg['from'] = formataddr((name, addrs)) \ No newline at end of file I found it in the discussion list. I don’t get compile errors, but Cleanse.pyc is not being updated. I have stopped and restarted Mailman and I have also rebooted, but same non-action. I have not tried ‘compileall’ and am not eager to, either (permissions, where to invoke, etc). Any suggestions? The host OS is Mac OS X Server 10.5.8 with Mailman 2.1.14 Yours, Allan

header field: Sender
by willi uebelherr 31 Mar '16

31 Mar '16

Dear friends, one question. If the Sender-field exist and mailman create a new Sender-field-line, then he have to delete the old one, or not? And maybe, this is true also for all other header fields, what mailman create? many greetings, willi St. Elena de Uairen, Venezuela

Allow discard-and-forward for spam filters?
by Adrian Pepper 30 Mar '16

30 Mar '16

Hello, Because of centralized administration of mailman server used by many campus units, and other general inertia, we still use 2.1.12 (a couple of local mods; I know of one for sure for recognizing alternative email addresses). So I am wondering if later versions of Mailman 2 have added something which seems to me to be obviously missing. In (showing a representative, not necessarily real, URL) https://python.org/mailman/admin/mailman-users/privacy/sender you can choose to "discard" most messages and check "forward discarded messages to the moderator". However, in https://python.org/mailman/admin/mailman-users/privacy/spam you can only Dicard or Hold. (Complete list Defer, Hold, Reject, Discard, Accept). It would be nice if for each filter rule individually you could choose "discard and forward to moderator". Has that actually been implemented in subsequent versions of Mailman 2, i.e. between 2.1.12 and 2.1.21 ? I assume in Version 3 the filter capabilities have been completely redone and probably regularized. It began to seem prudent for us to hold "slightly spammy" mail for inspection. A problem is that the majority of those would have been rejected by the sender filters anyway (though we're interested in those that wouldn't), so this has resulted in a lot of extra moderator work. Now certainly we wouldn't want [or would appreciate the choice not] to "forward to moderator" all discards on the /spam page. And, really, the "does this fail the membership (filter) requirements" is something you'd like to be able to determine in the spam filters. (And simply discard those, perhaps forwarding if they are not too spammy). (Because really really we'd like to "hold" slightly spammy messages which meet membership requirements, but discard-and-forward the others, but discarding-and-forwarding-to-moderator all would be reasonable compromise). I wondered too about combined expressions (and negation). Those don't look easy to do. header_filter_rules (privacy): Filter rules to match against the headers of a message. Each header filter rule has two parts, a list of regular expressions, one per line, and an action to take. Mailman matches the message's headers against every regular expression in the rule and if any match, the message is rejected, held, or discarded based on the action you specify. Use Defer to temporarily disable a rule. You can have more than one filter rule for your list. In that case, each rule is matched in turn, with processing stopped after the first match. Note that headers are collected from all the attachments (except for the mailman administrivia message) and matched against the regular expressions. With this feature, you can effectively sort out messages with dangerous file types or file name extensions. Since you can always add multiple rules to achieve "or", it seems unfortunate (but past history now) that multiple expressions don't "and". Anyway, my simple question is "did Mailman 2 sometime after 2.1.12 gain the ability to 'dicard and forward to moderator'" as an option for each spam filter rule? (Along with the implicit suggestion that that would be a useful option). (And the longer-term suggestion for AND and negation). Adrian Pepper

Re: [Mailman-Users] Mailman without localhost ?

The Service-Assistant of my hosting tried to solve, but did not found both of the default entries in mm_cfg.py. SMTPHOST = 'localhost' SMTPPORT = 0 So he's asking for accurate steps to handle SMTP Host Override (Plesk 12.5.x.). Also he wants to know, how to prevent overriding that values during next server-update. K.

Renaming a list
by Chris Nulk 29 Mar '16

29 Mar '16

Hello all, We have come up a few times where a list was created incorrectly. Normally, we catch the mistake, delete the list, and recreate it properly. However, there are times when the mistake is caught after having been in use. So, the delete and recreate is not available to use. I have a copy of Mark's clone_list command and it will allow us to rename lists. Which is great and not a problem for me. However, I am not the person normally involved with list creation, etc. Another group does it. Normally through the web interface which works well for them. Unless a mistake is made then they have to use the command line tools. Again, not a problem for me but that group has very limited knowledge of linux/unix and Mailman. I can easily train them to use the Mailman tools, however, ensuring they do the appropriate checks to avoid other problems is more difficult. Specifically, they can run the clone_list command but rebuilding the archives requires checking if the scrub_nondigest settings is No (this is explained in the clone_list help). What I have done is modify the clone_list command to combine the renaming/cloning of a list and include an option to rebuild the archives. However, the archives will not be rebuilt if the scrub_nondigest setting is Yes. Below my message is a diff of my changes to clone_list. While I try testing my changes on a test system, I would appreciate it if someone could take a look at my changes to ensure I am not off-base with my process.

Spam through my mailman?
by Michael Shulman 25 Mar '16

25 Mar '16

Hi, I am receiving spam to my list-owner address that appears to be sent from the same list-owner address. Here are some of the headers, anonymized a bit (google is there because my email is forwarded to my gmail address). Received-SPF: pass (google.com: domain of mailman-bounces(a)my.server.com designates MY.IP.ADDR.ESS as permitted sender) client-ip=MY.IP.ADDR.ESS; Authentication-Results: mx.google.com; dkim=pass header.i=(a)my.server.com; spf=pass (google.com: domain of mailman-bounces(a)my.server.com designates MY.IP.ADDR.ESS as permitted sender) smtp.mailfrom=mailman-bounces(a)my.server.com DKIM-Signature: v=1; a=rsa-sha256; q=dns/txt; c=relaxed/relaxed; d=my.server.com; s=mcmaildk; h=Sender:Content-Type:Date:Message-Id:MIME-Version:Subject:To:From; bh=(STUFF) Received: from localhost ([127.0.0.1] helo=www.my.server.com) by my.server.com with esmtp (Exim 4.84) (envelope-from <mailman-bounces(a)my.server.com>) id 1ajRhe-0006bB-4A for listmaster(a)my.server.com; Fri, 25 Mar 2016 08:23:06 -0500 Received: from [SPAM.IP.ADDR.ESS] (helo=spammer.domain.com) by my.server.com with esmtp (Exim 4.84) (envelope-from <mylist-owner(a)my.server.com>) id 1ajRhW-0006b2-Jk for mylist-owner(a)my.server.com; Fri, 25 Mar 2016 08:23:00 -0500 From: A.

Is there some way that my mailman may be misconfigured that could be allowing the spammer to spam through it in this way? Or has my server been hacked? Thanks!! Mike
