Transport Based on Domain
I'm running ISPConfig 3 with Postfix and love it.
I've been asked to create a domain that people can log into from a remote location, but only send and receive email to that domain. Only this domain should be affected (external email to this domain should bounce and also external smtp from this domain to another domain should be prohibited). Yeah - it's stupid - but so is the management that came up with this scheme (I fought them on this for hours)!
I saw a "mail_transport" table, but didn't see any reference to that in the docs. Can a guru help me out with some suggestions to handle this?
