For those of you using Postfix: Sendmail is the MTA of choice for RH-style distros. Instead, I use Postfix for reasons I won't get into here. Last night, Postfix stopped working, with a "mail to xxxx loops back to myself" error.
The fix turned out to be properly setting up the "match-clients" line in a /etc/named.conf file on the internal name server machine. This drove me nuts, because ping and traceroute on the Postfix machine found my mailserver (via /etc/hosts), but Postfix could not, because it wants to talk to the internal DNS server (and couldn't). That is broken (or at least misleading) behavior, IMHO. So, this message is a warning to any of the rest of you having Postfix problems to verify your DNS behavior with "dig", and to not rely on /etc/hosts.
