If it would be from domainX to domainX, there would be the
error
message "554 Sender address rejected: Invalid
sender".

These setting are only related to the RFC822 headers, not
the SMTP
envelope.

If you want to allow that external relay to be able to send
such
mail without verification, you need to add it to your
"Privileged
Networks" in the web interface. This way you circumvent
many of the
policy checks Kolab usually provides, but this is the way to
go if
you really want that.

Please tell us if it works for you.
