An e-mail was received from the fedora list.
Its sendmail assigned ID is i2MIAIw10942
Msgid=1079996878 4121 5 camel phantom

Now, for some reason, an e-mail from root has been received with
the same msgid, but a new sendmail ID of i2MIAJ810945

Finally, the original message with ID of i2MIAIw10942 has
been sent to your mailbox. The local mailer was selected.

...and now another e-mail has been received from root with the
same msgid, but a new sendmail ID. Huh!!!

..and this vicious loop continues until max hops. 

In a perfect world, each inbound e-mail should generate a pair of matching
sendmail ID's. One for the from: address and one for the to: address.
Example:

To be honest, I have no idea whay the above is happening. This could very
well be a routing problem that sendmail does not know how to deal with, but
I'll be damned if I can see it.

I hate to admit, but I'm out of ideas. Sorry!
