Hi, I'm trying to configure ISPConfig3 to relay mail for a domain to another host - no local users. I'm getting Recipient address rejected: User unknown in relay recipient table when I send a test mail. Configuration is as follows: Email routing: domaina.com No MX enabled, destination is set to IP of destination server Relay recipients: @domaina enabled. As far as I can tell this should produce a working configuration, fqdn of server is server.domainb.com so I don't believe that's the cause of the issue. Thanks Rob
