Subject: Someones forging our majordomos address

Hi,

Somebody used our majordomos address as sending address for his spamrun.
Now we are drowning in MAJORDOMO ABORT messages, because majordomo gets 
hit by thousands of Bounces.

I know I can filter my personal mail with procmail, but I would like to 
do this globally.

Is there a way to get majordomo not to send out these messages (but 
only for the mailerdaemon case, otherwise these alerts are often 
useful)?

I have tried to actually block mail from <> to majordomo using 
sendmail/AccessDB/check_compat-Feature. However, there seems to be a 
syntax-problem.

Check_Compat-Ruleset needs the fully expanded aliases and majordomo 
expands to "|/usr/local/lib/mail/majordomo-current/wrapper majordomo", 
putting this into a Compat: entry does not work (The AccessDB is 
processed without error, but the rule does not work).

Compat:<><@>"|/usr/local/lib/mail/majordomo-current/wrapper majordomo" 
ERROR: 550 Leave our majordomo alone
(I have tested Compat:<><@>user@domain and it works, it is only the 
majordomo part that goes wrong.)

Does anyone know, what the right syntax is?


thanks for your input

Susan
(Did I mention, that I hate spammers. There are millions of other 
addresses they could steal from our namespace, but no - it has to be 
the listservers, just to annoy us.)
