Can't help too much with the fix for the looping (I have similar poblems but
can't figure it out) but there is a way to stop it. I have used the
taboo_headers def in the list.config file to stop the loops. You need to
first define a custom message_header something like 'X-Mailing List:' then
add the appropriate regex in the taboo_headers section to catch it. Sorry I
don't have the exact var names or regex but you can find plenty of examples
in the md list archives (even if they are out of date) at
http://www.greatcircle.com/lists/majordomo-users/. You can do this globally
as well by doing the same in majordomo.cf.
Hope it helps.

Subject: Re: Sendmail sending listpostings more than once
I had this problem once, and it has nothing to do with sendmail itself.
One of the list members was redirecting mail back to the mailing list
*without* any changes to content within the mail message. By doing
the message appeared to be coming from an authorized user and therefore
majordomo happily sent out this duplicate message to the entire list.
way to spot this problem is to take a look at the received headers of
duplicate, you will see the are many more headers in the duplicate than
