[Mailman-Users] Interesting problem with gmail users
Note: this is NOT the frequently asked question about why GMail users don't see their own posts. I run a bunch of mailman mailing lists, and I'm subscribed to those lists from my GMail account. I also set up a filter to tag the posts from those mailing lists. However, the messages from some other GMail users on those mailing lists show a banner that says Due to a filter you created, this message was not sent to Spam. Edit Filters. Other GMail users do not show that banner. The ones who do show the banner show it consistently for every message they send to the list (although not on messages they send me directly) and the ones who do not show the banner never show it. I've never seen it for a non-GMail address. I suspect it has something to do with the way GMail puts a DKIM-Signature and DomainKey-Signature on outgoing mail. Something Mailman is doing is making the signatures invalid. As a matter of fact, doing a Show original on a couple of the flagged messages seems to confirm that, with messages like Authentication-Results: mx.google.com; spf=pass (google.com: domain of geeks-boun...@list.xcski.com designates 69.164.214.240 as permitted sender) smtp.mail=geeks-boun...@list.xcski.com; dkim=neutral (body hash did not verify) header...@gmail.com So what are my options here? Can I strip out the DKIM headers within Mailman? Or should I just configure my mailserver to add a DKIM header? -- http://www.linkedin.com/in/paultomblin http://careers.stackoverflow.com/ptomblin -- Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org

If your list adds msg_header or msg_footer, that almost certainly breaks the signatures. If your list makes no alterations to the message body or subject or reply-to headers, it shouldn't break the signatures, but certain Python email library transformations over which Mailman has no control may break them anyway.

Can I strip out the DKIM headers within Mailman? Or should I just configure my mailserver to add a DKIM header? Beginning in Mailman 2.1.7, these signatures were removed. Beginning in Mailman 2.1.10, this removal was made conditional on the new mm_cfg.py setting REMOVE_DKIM_HEADERS which defaults to No. So, assuming your Mailman is 2.1.10 or later, you can configure it to remove the headers by putting REMOVE_DKIM_HEADERS = Yes in mm_cfg.py. -- Mark Sapiro m...@msapiro.netThe highway is for gamblers, San Francisco Bay Area, Californiabetter use your sense - B.

Edit Filters. I guess it's just a Google thing now, not a Mailman problem. But if anybody on the list has any insight into that banner and how to get rid of it, I'd like to hear it. -- http://www.linkedin.com/in/paultomblin http://careers.stackoverflow.com/ptomblin -- Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org

Google knows better than you do what kinds of headers they're supposed to see on messages that claims to be coming from senders on Gmail. If you don't have those headers on your e-mail (maybe your mailing list management software removed them), then that would be likely to cause problems. -- Brad Knowles b...@shub-internet.org LinkedIn Profile: http://tinyurl.com/y8kpxu -- Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org
