need help blocking emails to non-existent users

[Kevin Miller]

I'm using sms-sav to do that - it works quite well and is free.  Another
good solution is milter-ahead, although there's a reasonable charge for
it.  sms-sav is on sourceforge if memory serves.  Certainly google will
find it if not...

Subject: need help blocking emails to non-existent users


I am currently running a mailscanner box on centos using sendmail that
relays to my exchange server.  I am trying to block email to
non-existent users at the smtp level on the MX. I understand I have to
somehow update sendmail with existent users in the active directory
possibly using ldap. I can't seem to find any good documentation on how
to do this. Many entries in the archive point to
http://www.mailscanner.info/serve/cache/270.html but this doesn't exist
anymore. I also found a sketchy bash script at
http://the-jer.spaces.live.com/blog/cns!E4FBBD09FA146AF!128.entry but I
don't like this approach either. I want to do all the work on the
gateway. Can somebody point me to some good documentation or a healthy
script that I could use to accomplish this?
