Created transport.db with
userdomain.edu smtp:{1.2.3.5}
and added to main.cf and did a reload

my test to userdomain .edu goes to the new server, but is refused
connection ...
Jun 5 12:27:09 b postfix/lmtp[4427]: 34D4CC00217: to=<userdomain.edu>,
relay=none, delay=0.01, delays=0.01/0/0/0, dsn=4.4.1, status=deferred
(connect to b.domain.edu[/var/lib/imap/socket/lmtp]: Connection refused)

do I need to add something to main.cf on b.daomin.edu to accept these
connections?
