He goes on to state that whenever TRANTOR goes down, CAMELOT tries to
deliver to TRANTOR and on failure, opens a 'connected to itself' which is
the problem. Apparently, the list of MX forwarders is not trimmed to
those with lower preferences than itself. This used to work on Ultrix
3.1.
We've run into the same problem here at our site. I was looking thru
comp.unix.ultrix for a response to the original note but couldn't find
it. Does anyone what changed in sendmail (or whatever) between Ultrix
versions? Thanks.
