Robert, Aidas Kasparas touched on this, but the "right" solution to your issue is not to go the /etc/hosts route, but to make sure that the DNS accessed by the Courier server resolves whatever it is you deem essential -- in this case, as I understand it, its own hostname. So you can prevent the problem you experienced by having a local DNS server that resolves the Courier server's own details. I tend to run a two zone server that responds to queries from localhost only, and which gets its zone data from the "real" DNS system (I probably should go some automated zone XFER mechanism, but since it gets updated so infrequently I just copy the db files around...).
