I just had an interesting problem.

We use a trouble ticket system here that works by receiving email, reading
its file from /var/mail and entering those messages into the system. It
does not run on our mail server, but rather on server1. Only the trouble
ticket user should receive mail on server1. Server1's MX is set to our
mailserver. Mail to troubleticketmailserver currently gets forwarded via
/etc/aliases to troubleticketserver1. My transport table has:

server1.dom.ain :[server1.dom.ain]

main.cf is set properly. This works.

Just this morning we added a whole bunch of new systems to our
architecture. All MX records point to mailserver. I have a file,
mydestinations, which is basically sendmail.cw -- it has each thing that
the whatever portion of an address can be for our site. I noticed a few
missing, among them server1. After adding server1, all hell broke loose
because mail went into a loop.

My question: should I be using a transport map for this, or would a
canonical map be better? I need all mail for userserver1 to go to
server1 rather than to the MX for server1, which is mailserver. 99% of
the time, mail to that userserver1 is coming from mailserver, which is
forwarding mail received for our customer service department.
