Well, that got resolved.  Someone had misconfigured 
their copy of Lookout! and was sending every message 
they received back to the list as a return receipt.  
Lookout! hadn't changed the headers, so it looked like 
the original sender was re-posting the message.  Postfix 
stopped the duplicate message and sent the confusing 
error message.

Looking at the Postfix log, and a raw view of the error 
message showed me which SMTP server the message 
was coming through.  I used the find_member command 
and lucked out - only one (former) subscriber from that 
domain.

[Mailman-Users] Forwarding loop?

[Mike Avery]

I've been getting the following error message every time 
I send a message to a list.  A number of other users have 
commented that they are getting the same message when 
they send a message to the list.  The message subject is 
Undelivered Mail Returned to Sender.

-- error message --
This is the Postfix program at host mail.otherwhen.com.

I'm sorry to have to inform you that the message 
returned below could not be delivered to one or more 
destinations.

For further assistance, please send mail to postmaster

If you do so, please include this problem report. You can

[EMAIL PROTECTED]: mail forwarding loop for
[EMAIL PROTECTED]

-- end of error message --

I looked, and the list is not subscribed to itself.   And the 
messages in question are delivered to the list.

System description - AMD K6-3, 450mhz, 128 megs of 
ram, FreeBSD 4.3, Postfix 2.??, and Mailman 2.06.

I'm pretty sure this isn't a Postfix issue, and I am 
confused.  

Does anyone have any ideas what might be causing this?

Thanks,
Mike
