[SOLVED] DKIM signing on postmaster@example.com messages

[poetry]

Hello,

Is it possible to enable DKIM signing on postmaster@example.com messages that come from the filter. If I look at GMAIL I see that the messages are not signed by DKIM.

From: postmaster@example.com Using MIME-tools 5.509 (Entity 5.509)
Subject: test DKIM SPF
SPF: PASS with IP
DMARC: 'PASS'

I have added all required records DKIM, SPF on DNS and enabled for postmaster domain but it's not working


Is this just not implemented or? This message would be delivered to sender if you use Action Object - Notification - notify __SENDER__

see: https://bugzilla.proxmox.com/show_bug.cgi?id=2971
the current DKIM implementation in PMG considers the envelope-sender - not the one in the from header
and for notifications from postmaster this is usually empty

I hope this explains it.

This now presents a serious problem.
I have mail held in quarantine for obvious reasons....
Some need to be forwarded, (whitelist, accept) because postmaster mail is non-signed the forwarding is blocked by receivers that require DKIM signing as premise. (the whitelist/accept mail should be sent with DKIM, or using an SRS address based on the original receiver).
How to proceed on this.
