> I'll check with Claus to see if he remembers.

Claus still had the mail archive from back then.  It was my scenario.
Specifically, Linux systems with certain versions of glibc would append
the domain/search in /etc/resolv.conf causing localhost lookups to
possibly return offsite systems.  This would of course cause problems
with mail delivery.
