Hi at all.
Actually, we make relay to other servers; an example.
Domain: example.com
mx: scalix
when the mail arrive to our scalix, filter spam and av and in the mailertable, relaying to other server. this is ok, but: to control the number of mailbos of this domain, que create internet address, but the relay not verified if the mailbox exist. if i put the domain in the local-host-name, y have to create the mailbox standar or premium, but don't make the relay.
In definitive, i want to relay al mial that exist in scalix. if the accont don't exist, reject if no, relay.
Is posible?
Actually, we relay all mail, and the destination server, reject inexistent acconunts.
