mail being sent from bounce list address?
by Adam Morris 08 Apr '16

08 Apr '16

Hi all, I use mailman as part of cPanel to run some lists so am not as experienced as others. Wondering why the below happens, I thought when a message is sent to a list it should be sent from the sender to the list name. In this case there is a bounce address mentioned.

Prevent unsubscribed users from being resubscribed
by Bjoern Franke 07 Apr '16

07 Apr '16

Hi, we are using mailman in one case for sending newsletters to customers. If they unsubscribe themselves from the list, it should be prevented that someone can add them again accidentally. Is it possible to use somehow a blocklist for mailman? TIA Bjoern

Mailman and recipient spam filtering
by Andrew Daviel 07 Apr '16

07 Apr '16

How does mailman handle recipient's spam filtering, if a message gets through the mailing list filters but is rejected by a recipient ? I have an incident where a rejection message was forwarded to a list, and on to other members. I don't know if that was even mailman, but it got me thinking. For instance, as a recipient's mailserver, we have various SMTP permanent rejection status returns: 550 5.1.1 user is unknown - mail will never work and you might as well unsubscribe me 551 5.0.0 Invalid recipient; Use <joe(a)example.com> - if you were really clever you'd auto-update the list membership, otherwise might as well unsubscribe me 553 5.3.0 Rejected by CBL - sending ip address is listed in a DNSBL and I won't accept mail until you get off the blacklist 550 5.7.1 Rejected by SpamAssassin milter - this particular message is too spammy (says I won $1M worth of viagra, for instance) and I won't accept it, but otherwise it's OK; don't unsubscribe me 554 5.7.1 Virus xxx detected by the ClamAV AntiVirus - this particular message has a virus or phishing document and I won't accept it, but otherwise it's OK; don't unsubscribe me which are probably inconsistant, created over a span of many years -- Andrew Daviel, TRIUMF, Canada Tel. +1 (604) 222-7376 (Pacific Time)

Which autoreplies are configurable
by Adrian Pepper 07 Apr '16

07 Apr '16

Is the following reply configurable in any Mailman 2 versions? --===============4977805536057818275== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit You are not allowed to post to this mailing list, and your message has been automatically rejected. If you think that your messages are being rejected in error, contact the mailing list owner at mailman-users-owner(a)python.org --===============4977805536057818275== Content-Type: message/rfc822 MIME-Version: 1.0 (In this message I have changed the actual list name and owner as if the name of the list is mailman-users(a)python.org to reduce exposure of the actual list). As far as I can tell, the only configurable email response settings are "held for moderation" https://python.org/mailman/admin/mailman-users/privacy/sender and "auto-response" (to successful postings) https://python.org/mailman/admin/mailman-users/autoreply autoreply.autoresponse_admin_text And the welcome results. https://python.org/mailman/edithtml/mailman-users/subscribeack.txt ("subscribe results" is something different).

DKIM, SPF, DMARC, Mail_as_list all working, but MUAs not happy
by Arlen Raasch 05 Apr '16

05 Apr '16

All: I am using a very old version of mailman, 2.1.16. I wanted to update to a newer version during this migration, but I was too concerned that I would break something in this complex server by upgrading and changing the dependencies that new versions of mailman require. A large number of our users are not happy with how mail is presented when Mail_as_list is active. They messages appear as attachments in some MUAs. If I change from Mail_as_list to Mung From, DKIM does not validate. I noticed from previous emails I received from this list that DKIM does not validate here either. Can I just switch the list to Mung From with some certainty that the email providers will continue to relay our traffic as we have valid SPF and DMARC records? Would switching to a later version of mailman make this any better (and why)? Thanks in advance, Arlen Raasch

New Mailman 3 users list
by Mark Sapiro 05 Apr '16

05 Apr '16

I'm happy to announce a new list for Mailman 3 users and others interested in Mailman 3. This list is running on a new Mailman 3 installation at lists.mailman3.org. The list's posting address is <mailman-users(a)mailman3.org>. The list's info page is <https://lists.mailman3.org/mailman3/lists/mailman-users.mailman3.org/> and its archives are at <https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/>. The top level Postorius page is <https://lists.mailman3.org/mailman3/> and the HyperKitty archiver is at <https://lists.mailman3.org/archives/>. You can subscribe by email by sending a blank message to <mailman-users-join(a)mailman3.org> and responding to the resulting confirmation request. You can also subscribe by going to the info page at <https://lists.mailman3.org/mailman3/lists/mailman-users.mailman3.org/>, logging in and subscribing. Log in offers three options. There are Google and Facebook OAuth2 login links on the log in page to log in with a Google or Facebook account, and there is a 'Login by email' link to login via Persona with any address you register and confirm with Persona. This is a new installation of Mailman 3 so there are still kinks to work out, and any issues can be discussed on the list or reported to the trackers at <https://gitlab.com/mailman/postorius/issues>, <https://gitlab.com/mailman/hyperkitty/issues> or <https://gitlab.com/mailman/mailman/issues> as appropriate. Enjoy! -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B. Dylan

Mailman not supported on new server
by rex＠rexgoode.com 05 Apr '16

05 Apr '16

My host company has upgraded me to a new server at my request. After migrating things from my old server, I learned that they say that mailman doesn't work on the new server. When I try to create a new list using whatever it is they do support through the hosting company's admin interface, it tells me my lists still exist. I can use the mailmain admin to do administrative stuff, but if I try to send an email to the list, I get an error like below: SMTP Error (550): Failed to add recipient "mylist(a)mydomain.com" (5.1.1 <mylist(a)mydomain.com>: Recipient address rejected: User unknown in virtual mailbox table). I wonder if there is a way to get mailman to work and show my hosting company that it is still possible. Rex

Filtering Reply to list with informative rejection message
by francis picabia 05 Apr '16

05 Apr '16

We already have settings under General for stripping the original Reply-To and reply goes to list is set as Poster. We have experienced a case where nominations were solicited from the list members, and there was a response with confidential information which went to the list rather than the poster. There is a possibility management will want to block all replys to the mailing list. One could work around it by making a fresh email to the list. The Spam Filter rule to Reject based on finding "^In-Reply-To:" works well, but the simple rejection is not going to be understood by our users: Message rejected by filter rule match We can customize that in the source, but it would impact all lists. Holding for moderation isn't an option because we have enough volume and email outside of office hours that this wouldn't be workable. I see a way to send a custom message to non-members of a list. That won't fit. I see a way to send a custom message to moderate members, which we don't want either. Is there another option I have not covered or I have misunderstood something here?

Off topic, how to get in verizon.net's good graces?
by Arlen Raasch 04 Apr '16

04 Apr '16

All: We moved to a new server, new IP address and have SPF, DMARC, and DKIM working and being accepted by all the major email providers. We implemented Send_as_List as well. By inspecting the relayed email content we can see the major email providers are saying we pass on SPF, DMARC and DKIM. But, try as we may verizon.net still refuses to talk to our servers except to say it is rejecting our messages. Here is an example: Apr 3 06:53:13 www postfix/error[12377]: 4A718272B: to=< verizonclient(a)verizon.net>, relay=none, delay=0.12, delays=0.03/0.06/0/0.03, dsn=4.0.0, status=deferred (delivery temporarily suspended: host relay.verizon.net[206.46.232.11] refused to talk to me: 571 Email from 192.168.1.1 is currently blocked by Verizon Online's anti-spam system. The email sender or Email Service Provider may visit http://www.verizon.net/whitelist and request removal of the block. 160403) The email address above is changed as well as the IP address of our email server. I have submitted multiple whitelist requests as shown above, and have seen no response whatsoever from Verizon. Frustrating. This has been going on for 5 days now. I am about to send emails out directly to our list subscribers asking them to migrate to another email provider, but thought I would ask the list if anyone else had any success with verizon.net and how they did it. Thanks in advance, Arlen Raasch

List Migration Questions
by Richard Robbins 04 Apr '16

04 Apr '16

I administer a mailman mailing list that is hosted by a web hosting company. I am in the process of identifying a new service provider and want to migrate the mailing list and hope to move the archives. The customer service people I have contacted do not seem to know much about mailman and I am concerned that they might not be able to get me the relevant mbox file. The archived messages in monthly chunks are publicly available so I was hoping that there might be a way for me to access the mbox file without assistance from the hosting company. In the alternative, what directions should I give the hosting company to locate the file. If I can't get the mobx file is there any way to reconstruct it from the monthly gzip collections so that my old messages can be integrated smoothly into a list established with another hosting company? Thanks for your guidance. -- Rich
