Hi there,

I'm trying to achieve configuration that would verify DKIM signatures
for known signers.
Everything works fine until envelope-from address is one of known
signers. But many spams have envelope-from set differently than From:
header, eg. [email protected] in envelope-from and
[email protected] in From: header.
This enables them to bypass DKIM signature checks and therefor to bypass
one of the anti-spam mechanisms.

How can I instruct exim to include From: headers' content in known
signers checks?

Regards,
