[Mailman-Users] Strange DKIM failure
Hello list. I'm running a Centos 7 mailserver with multiple domains. I create a list for one of them and found at code 2 lines of DKIM: dkim=pass (1024-bit key) header.d=... dkim=fail reason="signature verification failed" (1024-bit key) header.d=... I guess that was the reason that many recipients didn't receive any email, especially yahoo users. Why there are 2 lines of Dkim and why the second is fail? SPF and DMARC are pass. Direct email from the same domain users DKIM, SPF, DMARC are pass. Can someone help me? Thank you, Nikos. -- Mailman-Users mailing list -- mailman-users@python.org To unsubscribe send an email to mailman-users-le...@python.org https://mail.python.org/mailman3/lists/mailman-users.python.org/ Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: https://www.mail-archive.com/mailman-users@python.org/ https://mail.python.org/archives/list/mailman-users@python.org/

No, my list is like listn...@domain.com and the sender is like u...@domain.com. I have check the host name in the first page of General Options Section. The owner is different, ad...@otherdomain.com, witch is the administrator of the mail server. Thank you for your answer.

Hi Nikos, Is the domain part of your the address used for the mailing-list the same as the domain of the direct email? I had a similar issue when our direct emails bore something like some...@domain.com while the mailing list bore listn...@mail.domain.com. Eventually we had to create SPF, DKIM, DMARC keys/selector specific to mail.domain.com to solve that.

If you want to munge user and domain names, you can, but do so in a way that we can tell what's what. -- Mark Sapiro The highway is for gamblers, San Francisco Bay Area, Californiabetter use your sense - B.
