My system is being hit hard by spambots who send messages that look

Courier's own criteria, and each such rejection generates a DSN.
These DSN's end up being sent to non-responding addresses, which
causes them to be deferred in my mail queue.
Needless to say, this causes two undesirable side-effects on my system:
1. An ever-increasing number of deferred messages in Courier's
queue.
Normally, Courier does not accept mail addressed to nonexistent local
mailboxes. You must have some unusual configuration which accepts all mail
and bounces nonexistent recipients internally.
I forgot to mention that many of the spams are being sent to
postmaster at my host, which is an existing mailbox. This large
group of spams are being rejected by courier because their "from"
address is illegal: <#@[]>
If not, can anyone suggest a different solution to the problem I
outlined above?
Undo whatever you did to force Courier to accept mail to nonexistent
addresses.
