spam discard expressions
by Jim Dory March 8, 2018

March 8, 2018

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 . Nov. 2, 2017

Nov. 2, 2017

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

Postfix delivers to mailman, but not aliases
by James Dore Oct. 26, 2017

Oct. 26, 2017

Hi list, I recently migrated our mailman server from an old SLES 11 box to Ubuntu 16.04.3 LTS, and installed Mailman from the Ubuntu repositories along with Postfix and other prerequisites. Mailman itself is working fine, but I have a handful of regular email aliases in /etc/aliases which do not receive mail, and when examining the logs, get bounced with a “User unknown” error. What did I screw up? (I’ve checked my aliases and they’re good, and I’ve run the newaliases command numerous times).

integrating mm3 with postfix / lmtp
by Fabian A. Santiago Oct. 25, 2017

Oct. 25, 2017

Hello, I have mm3 up and running via docker (courtesy of maxking/docker-mailman) but when i send an email to my test list, it bounces back claiming user unknown. it states: <"lmtp:[172.19.199.2]:8024"@>: unknown user: "lmtp:[172.19.199.2]:8024" looking at the email source, it seems as though the message is trying to be delivered to: Final-Recipient: rfc822; "lmtp:[172.19.199.2]:8024"@<my email server's FQDN> Original-Recipient: rfc822;test123@<my list's email domain> all of various alias transport maps are defined in postfix's main.cf. not sure where to go from here. does anyone have any clues? -- Thanks, Fabian S.

cause of bounces
by paul＠tokyoprogressive.org Oct. 24, 2017

Oct. 24, 2017

Hi and hope the answer(s) to my question are relatively simple. On one of two lists I manage, some people are getting deleted due to too many bounces. And the bounces seem to be related to their mail provider not allowing the messages. As far as I can tell, the main culprits are gmail, yahoo, and hotmail. Of course, those people blame Mailman. From what i have read, it is not necessarily that. But complicating things is that people were complaining that the default REPLY to SENDER was not appropriate for a discussion list, so I just switched it over to REPLY TO GROUP. I do not THINK that is the reason for the trouble, but here in the space of a few minutes are some of the messages I have gotten with my questions in caps. PROBLEM ONE UNABLE TO SEND? RECEIVE? a(a)yahoo.com <mailto:a@yahoo.com> host mta7.am0.yahoodns.net <http://mta7.am0.yahoodns.net/> [66.196.118.37] SMTP error from remote mail server after end of data: 554 5.7.9 Message not accepted for policy reasons.

Mail Delivery
by David Andrews Oct. 18, 2017

Oct. 18, 2017

At one time I set Reply-To: header munging under general settings to Yes. Some of my users used a screen reader that balked unless the header was munged, for some reason. Well that software has gone away, and ISP's are much pickier these days, with MARC and dkim and SPF etc. Would this setting cause me delivery problems ?? Should I go back and change it on older lists. I no longer set it to yes, leave it at no, its default. Dave --- This email has been checked for viruses by AVG. http://www.avg.com

DKIM signing issue - relaying mailman e-mails from third party sources
by Dlugasny Oct. 12, 2017

Oct. 12, 2017

Hallo Mark, Kolleagues, maybe somebody will be able to help me here. I would like to relay (also check with Antivir and sign them with DKIM) all Mailman e-mails from our external partners to our final customers. Relaying seems to work nice but we have a problem with DKIM authentication and Return-Path. Mailman server needs to stay by external partners with old domains and needs to receive bounces. My SMTP gateway is only responsible for receiving and sending e-mails out from the all mailman instances. The problem is that we are sending an E-mail which looks as follow: From: campaign(a)myserver.com Return-Path: mailman-bounces(a)external-company.com To: @gmail.com The problem is that DKIM check on the gmail server server (and all others) returning error: [...mailman-bounces@external-company.com](mailto:mailman-bounces@external-company.com) does not designate xx.xx.xx.xx as permitted sender How to solve that issue ? At the moment we have a DKIM key only for myserver.com. Why DKIM check checking Return-Path and not From address ? Could You please help here how to manage that issue ? We simply would like to forward all messages from the external mailman instances installed on the different domains to the final customers using our sender domain [myserver.com.](mailto:campaign@myserver.com) I will appreciate any feedback from Your side. Cheers Dlugasny

Wish list: bounce notifications
by Jordan Brown Oct. 11, 2017

Oct. 11, 2017

My mailing list is hosted on a low-cost service with shared servers and so a couple of times a year some other customer gets them onto a spam blacklist and mail starts bouncing. I need to know about those situations ASAP so that I can prod the provider into fixing the problem and requesting delisting, but Mailman doesn't seem to have a way to tell me when it gets a bounce... only when it's gotten several bounces and disabled a membership. Since I don't want to wait for several bounces, I have it set on a hair trigger; it disables people on the first bounce and so I immediately get a notification. That works, kind of, but it means that I have an extra re-enable step to repair the damage and that if I somehow drop a notification on the floor I can leave somebody disabled. What I'd like would be a way to ask Mailman to notify me on *every* bounce, without disabling the user. (Or, of course, if there's just something I've missed in the config pages, please educate me.)
