Enable the use of relaxed/relaxed canonicalization - DKIM configuration in Kerio Connect. (c=relaxed/relaxed)
Currently the canonicalization is hard-coded and cannot be changed.
As stated in the article "Adding DKIM and DMARC Records to Kerio Connect".
This setting is requirement for some mail forwarders (like Microsoft) who "fix" headers or message body to match their standards.
Change to the header or body with simple/simple setting causes the DKIM check to fail on the receiving end.
This causes the DMARC to fail and the mail being quarantined or ignored (when configured as so with DMARC).
Thank you.
