Using PMG as a smart host, the issue in running into it the scan on attachments on 10023 which causes a reinjection, when I remove the content filter scan, pmg acts as a transparent host and it works fine without being able to apply any filtering rules.
PMG is setup with SRS and ARC.
ARC verify attached to port 26 and sign to 25 through the master.conf
Most mail flow works expect when the email starts from Gmail goes to the server and is forwarded to PMG and back to Gmail.
Without content filter and with or without attachments.
Dkim pass
Spf pass
Dmarc pass
ARC pass
Cv=pass
With content filter and clamav off and with attachments.
Only spf and dmarc pass.
Report safe is set to 0 and no filter is applied in the Ui.
What internal content filter would be causing a rewrite that would break DKIM.
