Absolutely, unfortunately I've never managed to convince them to generate
delivery  errors that  can be  understood  by mortal  men. The  offending
address is either postmaster@MINT  or postmaster%mint@CERNVAX, and it's a
good idea to SERVE it OFF.

LISTSERV isn't dumping anything. That funny:
 
>To: Andreas Magun
>    <S=magun;OU=iap;OU=sun;ORG=UNIBE;PRMD=UNIBE;ADMD=ARCOM;C=CH>
 
is simply an  X.400 address. Welcome to the world  of Standard Protocols,
Herb!
