Sounds like something in your router isn't set up right.  Could be a dead
entry if it's just forwarding DNS queries (usually the case with
off-the-shelf routers) or could be having problems with root lookups.

Everything here looks right, though I'm making a few assumptions about your
network setup.

Well, it certainly narrows it down.  There isn't an entry in the hosts file
for your smtp server, so it has to be in the DNS.  I don't know much about
postfix, so about the only thing I can think of is that it's timing out
looking up the entry, but that's a wild guess.

I'd check that your router is set up properly and try it again.

Good luck!
