Proxmox Mailgateway: SPF / DKIM / DMARC Check and Header

[sysadminfromhell]

Hello everyone,

yesterday I switched to PMG so reduce the the cpu usage on my mailserver. So the pre-checks are made somewhere else so the Cloud VPS stays cheap.
Now I got a question: Is it possible to set a header if spa/dkim/dmarc fails or is it just the SPAM Score which gets higher?
I would like to use the headers still.

Kind regards,

Failing DKIM/SPF detection is done through SpamAssassin currently - and this does not set a dedicated header.

You can add the __SPAMINFO__ as a header - this will contain the names of the SpamAssassin hits on which you could match.

else see https://bugzilla.proxmox.com/show_bug.cgi?id=2517 - we're currently not actively working on that (and we'll wait at least till SpamAssassin 4.0 is out to see if that brings some different support for such things) - but you can subscribe there to get notified if this gets implemented

I hope this helps!
