And therein may be some clues? Make sure /etc/resolv.conf is right, you
may resolve *completely* from /etc/hosts (or any ldap/yp/nis/...? that
is running in your net?) or you may have a local bind that needs
configuring as a (non-)caching DNS server?

/var/log/maillog can be your (very verbose) friend (with whom I am
empathetic! *chuckle*).
