<p class="MsoNormal"><span lang="EN-US">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">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/<o:p></o:p></span></p>
