I am setting up to use a service from an external company that utilizes
SMTP for messaging via a non-standard port. So to be clear - this is
*not* for standard mail!
Given a recipient address in the form "s123...@example.com", and I'm
given the IP and port, do I just need to define an entry in my transport
map? E.g.:
s123...@example.com 1.2.3.4:5525
Do I need to define anything for relay_domains or anything else?
Separate question - since my own server is *not* an open relay and only
permits authorized users, how do I allow that external address to either
be used as the sender (which I'd rather not) or re-write my authorized
sender for the relay?
