Mails are not being signed with ARC latest build

draven

Hey guys I found something while testing, you can try yourself. in the latest build I noticed that my emails are DKIM pass SPF pass and DMARC pass, but ARC is not included in results.

Perhaps in a older build I got this working like a charm and being recognized by google.

Here is an example:

Current cow version:
ARC-Authentication-Results: i=1; mx.google.com;
dkim=pass header.*****
MISSING ARC
spf=pass (google.com: *****
dmarc=pass (p=REJECT sp=REJECT****

Older cow version:
ARC-Authentication-Results: i=2; mx.google.com;
dkim=pass header.****
arc=pass (i=1); ***** <========= there it is.
spf=pass (google.com: *****
dmarc=pass (p=REJECT sp=REJECT *****

hopefully we can find a fix or solution to this soon, have a good one.

ARC is signed inbound.

Ok I understand what you mean, perhaps there is a difference and let me show you a comparison
utilizing Microsoft Office 365 Mail Service, an older MailCow version and latest build.

Sorry looks like I can’t post images probably because I am totally new to this forum.

Those emails were sent directly to gmail and It seems that there is something missing in this comparison, it appears to be affecting only the new version of MailCow,

How can I make it work as it usually did?

Thanks,
