Hi, Wietse. What an honor to receive this response from you :) > Checking application/pgp-signature: FAILURE Here the signature is validated correctly with Thunderbird and Mutt.

On that way users who are not in /etc/postfix/virtual are sent via relayhost. What do you think? Anyway maybe your solution is better because in the end all users will have to be in /etc/postfix/virtual :) Thank you for your time and interest. Much appreciated. Kind regards, Daniel
