to non-existent users<BR></FONT><BR></DIV>
<DIV></DIV>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 <A
href="http://www.mailscanner.info/serve/cache/270.html">http://www.mailscanner.info/serve/cache/270.html</A>
but this doesn't exist anymore. I also found a sketchy bash script at <A
href="http://the-jer.spaces.live.com/blog/cns!E4FBBD09FA146AF!128.entry">http://the-jer.spaces.live.com/blog/cns!E4FBBD09FA146AF!128.entry</A>
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? <BR clear=all><BR>-- <BR>Joey Marino
