Most MTA's have an option to set what names/domains for which it will
accept local mail. In other words, I could configure alfa to accept mail
for bravo if I wish, but by default it won't. If paul@alfa sends mail to
paul@bravo, and host alfa knows how to get to host bravo, mail should
move between hosts without any additional configuration.
In sendmail, you have the "local-host-names" file. In exim, the
exim.conf file has a line labeled "local_domains =". Both of these serve
the same functions -- to define what host names the host will accept
local mail for. To go even further, sendmail has the optional
mailertable, in which you can specify what host to send mail to
depending on the host/domain suffix.
