I just tried to enable the subversion feature, but I get the error message
Failed to save enabled features : Your Postfix configuration is missing the system's mail hostname domain.tld from the mydestination line, which will cause mail to bounce.
The hostname command returns 'host.domain.tld'.
The /etc/hosts file lists my external IP and host.domain.tld.
The postfix config is valid and all mails are delivered perfectly.
The only "non standard configuration" at the moment is, that domain.tld is still handled by my old server, while host.domain.tld is handled by the new server. I also tried to use domain2.tld and host.domain2.tld (which is completely handled by my new server) in /etc/postfix/main.cf - but the result was the same.
Any idea what might be the issue here?
Thanks a lot in advance!
