Hello, I have a simple relay for sending emails from internal scanners and a voicemail system. All works fine except for posts that get bounced as the bounce notifications somehow fail both SPF and DKIM tests.
The only (seemingly significant) differences I can find in the headers of normal vs bounced posts from the system are: Normal: Authentication-Results: test17.example.com; spf=pass smtp.mailfrom=u...@example.com Authentication-Results: test17.example.com; dkim=pass (2048-bit key) Bounced: Authentication-Results: test17.example.com; spf=none smtp.helo=smtp.example.com Authentication-Results: test17.example.com; dkim=none The normal mail has: smtp.mailfrom=u...@example.com and the bounced mail has: smtp.helo=smtp.example.com And so it looks like this difference is keeping the bounced notifications from passing SPF and getting processed by OpenDKIM. Suggestions? Thanks! Chris
