[Mailman-Users] Bounces from a funky address choke Mailman

[Igor S. Livshits]

Hi,

It seems that bounced messages from an address such as 
<stoutamire%biology%uakron at polskys.cc.uakron.edu> seem to crash 
Mailman:

    ----- Transcript of session follows -----
554 "|/home/mailman/mail/wrapper mailowner aergc"... unknown mailer error 1

Has anyone else encountered such behavior?

Thanks, igor
