I'm not on any of the majordomo elists, so I won't see any replis to the
list. (I don't admin majordomo, just help run a list at another site.)
Please pass along this fix to the appropriate elists and newsgroup(s),
plus insert the fix into the 1.94 release.
~/majordomo/patchinfo.txt
WARNING TO ALL MAJORDOMO ADMINISTRATORS: The patch below is required
to prevent infinite loops of bounced messages from nonstandard mailers.
I've been hit by another infinite loop of bounced messages problem
in a majordomo email list. The problem is that a mailer does not
properly follow the "Errors-To:" header and bounces messages to the
elist. Moreover, the Subject: header does not conform to the "usual"
mailer error message (Unix sendmail is the "standard" behavior used
by nearly all Internet email systems), thus majordomo can't catch this
bug.
--------------------------------------------------------------------------
The main problem is that mailers ignore (or lose) the "Errors-To:"
header. This problem should be reported as a serious bug, and corporate
and government CIO's should ban such mailers in thier organization.
(CIO's should also ban mailers that lose the From: address, but since
big names like Lotus/ccmail do this, it's probably a lost cause.)
To determine if a mailer has this problem, send email to a bogus
user in the domain, e.g. bogus@????????, and set the Errors-To: to
some other email address. (This may need to be done from outside a
proprietary email system to test a gateway.) If the message does not
bounce to the Errors-To address, this system could cause an infinite
loop if the subject line in the bounce message doesn't match a "usual"
email system.
--------------------------------------------------------------------------
Here is a patch to majordomo-1.93.tar.Z which will filter many of the
bounced messages that cause infinite loops, including some vacation
programs: (use "patch" or manually edit)

I sent a similar fix last year. If you applied these fixes, you need to
apply the following patch:
diff -c resend.9508 resend

For majordomo-1.94a3 users, the corresponding patch is:
