I'm setting up a new Scalix collaboration server for users at one location, but would like to relay non-local users (and aliases, and mailing list traffic) in the same domain to an existing external server for our other locations. Unfortunately I'm getting an error when attempting to send a message to a non-local user or alias.
In another message thread someone had the opposite problem and the answer was to add the local domain to /etc/mail/local-host-names, so I tried removing the domain from mine and restarting Scalix, but to no avail.
Is there something akin to Sendmail's LUSER_RELAY setting I can change in Scalix?
Thanks!
