[Mimedefang] Preventing bounces for spams

[Kevin A. McGrail]

Jason,

This is a Sendmail question and one I have been working on learning more
about as well.  However, my research points to the fact that a better avenue
is to configure your exchange server's built-in LDAP service to tie-in to
Sendmail's built-in LDAP support to simply reject the messages to unknown
users at the gateway server rather than accept, scan, forward and then
bounce.

Graham Dunn along with others have been discussing this in the archives and
have sent me down the path of learning about this as well.

Regards,
KAM

I'm using MD 2.38 with Spamassassin in a gateway machine with no local
delivery.  Emails hit this machine from the internet, get scanned, and
sent on to an Exchange server.

I'd like to set it up so that Sendmail will not attempt to send a bounce
message back to the sender for emails that qualify as spam.  Such as in
the case that a spammer sends a spam to foo at mydomain.com where the user
foo does not exist.

Any suggestions?
