I do believe this is a relatively simple issue to solve. but
haven't found it yet..
*my-relay* = internal relay
*master-relay* = internal and external relay
Setup
Sending host => *my-relay* => *master-relay*
relayhost = master-relay
Looping issue..
When the *master-relay* sends *my-relay* a bounced message *my-relay*
sees the destination and then sends it back to the *master-relay*.
I want my-relay to "receive" *all* email from the *master-relay*
and dump it into the Postmaster (alias) mailbox instead of sending it
*back* to the *master relay*..
What would be the best way to do this.?
