Cannot find answer - stop queueing messages?

My root mail fills up very quickly because we have hundreds of remote printers and whenever a job is deleted, moved or a printer is down, up, sidways (jk) the queueing system drops root and email.

It fills up super fast and is causing a problem.

Rembak is the backend but i cannot find a way to supress messages.

please help.

which platform ? version ?

AIX ver 5.1
