Amavis and OpenDMARC

[Dino Edwards]

Hello,

 

In the past I used OpenDKIM to sign and verify DKIM signatures. However
considering the fact that it hasn't been updated in a very long time and
constant issues with e-mails from O365 senders, I decided to give Amavis
DKIM a try. I have it configured and it looks like it works verifying and
signing outgoing e-mails. However, I seem to be having some weird issues
with OpenDMARC which I also use. OpenDMARC is setup as a smtpd_milter in
Postfix. For the most part, incoming e-mails pass the OpenDMARC test but I
have a few select ones that fail and get rejected. Now these e-mails from
the same senders would pass DMARC when I was using OpenDKIM. So the only
that has changed is using Amavis instead of OpenDKIM for DKIM verification.

 

Can someone maybe shed some light on why this would be happening or is there
a different way to handle DMARC? 

 

Thanks in advance.
