Greeting members,
I found that, after I enable opendmarc to reject messages, there are some
issues for list addresses. for example, this rejected message shows:
<t...@dkinbox.com>: host mx1.dkinbox.com[193.106.250.86] said: 550 5.7.1
rejected by DMARC policy for radlogic.com.au (in reply to end of DATA
command)
And I checked that, radlogic.com.au does have a p=reject policy:
_dmarc.radlogic.com.au. 3600 IN TXT "v=DMARC1; p=reject; fo=1;
rua=mailto:ad...@radlogic.com.au";
Following their policy, I have the permission to reject it.
Since the message was sent to mailing list which rewrites envelope address
and adds list signature, so:
1) SPF for header From: address won't get pass due to SRS.
2) DKIM won't get pass due to list signature.
So the DMARC failed totally and the message was rejected.
How to improve this?
Thank you.
Tom
