Sorry for the mailing loop problem.  It should now be fixed.
I have also deleted all pending messages the system was still
attempting to deliver.

If you notice any further serious problems, please contact
me +1 650 279 2500.

                                      thanks,
                                              gordon

Anyone interested in the cause of the problem feel read on...

My preference is to run on a platform that I have gotten
really reliable and secure, than constantly be upgrading to
the latest release.  But finally, last night, after 3 years
of use, I decided it was time to upgrade the mailserver from
RedHat Linux 4.1 to 6.2.  Or maybe I should really call it
CheapBytes Linux 6.2.

By default /etc/resolv.conf on RedHat Linux contains a line
like:

    search base.com

which says, if it can't find a host with the requested name,
try appending "base.com" on to the name, and then try again.

Normally, this wouldn't be a problem, except that I have
sendmail configured to map [EMAIL PROTECTED] to
[EMAIL PROTECTED]  I have sendmail configured this way, so
that every time I have to submit my email address to a
website, I can use a names such as [EMAIL PROTECTED],
[EMAIL PROTECTED], and that way keep track of whether
anyone is selling my address.

The final piece of the puzzle is there is an address on the
mersenne list:

    [EMAIL PROTECTED]

which for some time has probably been invalid, but not
previously causing any problem.

So, what was happening is a message was coming in for the
mersenne list, the system would start delivering it to
everyone, including [EMAIL PROTECTED], and
when it found this address was unresolvable, it would
append base.com on to it and try delivering the message to
[EMAIL PROTECTED], which because
of how I have sendmail configured, would map back onto
[EMAIL PROTECTED], and the same message would keep getting
reinjected back into the system over and over again.

The fix is simply to change /etc/resolv.conf to:

    search .

which is how I had been managing to avoid this problem in
RedHat 4.2.
