MTA/Perl script for relaying only to Exchange-users

[Rob Kettle]

Hi,

I'm running a task on my exchange server and on my sendmail box that achieve exactly what you describe but not perl based.

I'm not able to get the info right now but can do so tomorrow if you still need it.

Let me know if you want my take on it.

Regards
Rob

Subject: MTA/Perl script for relaying only to Exchange-users

Hi, for a couple of years ago there was a guide on mailscanner.info about restricting the MTA (Sendmail) to only deliver email to valid users in an Exchange environment. This made the performance of the server much better because either MailScanner or Spamassassin need to process invalid emails.

I remember that there was a perl-script which picked up the content from a textfile (with all smtp-addresses in the domain) and then build a special file in /etc/mail/

I can’t find this guide on the site. Anyone who can help me?
