[Mailman-Users] Two administrators : error message bomb

[Roger Slevin]

Over the recent holiday period one of two administrators mail systems was
down, and a list (running on Mailman 1.0) triggered a message to the
administrators.

The result was a mail bomb of 
"Mail delivery failed: returning message to sender"
 messages to the one administrator whose e-mail system was working, caused
by the bounced messages from the other administrator being re-sent to both
administrators by Mailman.

Is this a known bug?  Is there a patch?  Is it fixed in version 1.1?

Any help greatly appreciated - we've gone down to having only a single
administrator on each list for the time being to prevent this problem
repeating.
