Question about exim, mx, etc.
OK. I have finally gone to the virtual private network route on my
network at home. I've actually been doing that for a long time now.
Recently, I got a zoomy new PPro machine that is really fast. So, I
thought I'd have my gateway machine (running FreeBSD) act as a mail
forwarder for this new system. The gateway machine is rover, and the
new machine is harmony. So I setup the following in DNS:
Server: information-retrieval.village.org
Address: 204.144.255.51
harmony.village.org preference = 20, mail exchanger = information-retrieval.village.org
harmony.village.org preference = 50, mail exchanger = mroe.cs.colorado.edu
harmony.village.org preference = 5, mail exchanger = harmony.village.org
harmony.village.org preference = 10, mail exchanger = rover.village.org
... (name server info omitted)
This works *GREAT*. My email was flowing w/o a hitch to the new
machine. Then all of a sudden, something went wrong with the new
machine (well, a dog nosed the power switch off w/o my noticing it).
At that point, mail started bouncing on rover. Too many bounced.
Rover was sending this message to itself over and over again until the
hop count was exceeded. Later, when I tried it with harmony off on
purpose, same thing happened.
Ideas?

P.S. Here are my config file. I'm running exim 1.60 on FreeBSD
-current as of about a month ago. This is the freebsd port version,
which is nearly the stock 1.60 version, except for log file location.
