Can't tell for sure but it might be an issue with files be shifted around 
or anything. In my sendmail days I had a seperate directory with my 
sendmail.mc file (actually it use to be a <YYYYMMDD>.mc file) so I could 
keep track of my changes. I had quite a few tricks in there to hold of 
spammers and it was one of the reasons I was slow in picking up postfix.

Just copy the file to a new date, add a function or remove it and compile 
it. Then move the <YYYYMMDD>.cf file in place and give sendmail a nudge to 
read the new config file. This 1 change, 1 version strategy is great for 
troubleshooting.

In those days I could do quite some tricks in sendmail for which I did not 
see an equivelent in postfix.

These days I can do quite a few tricks in postfix and it would take me 
some time to work out their equivelants in sendmail.

If you know your MTA you can do a lot to stop SPAM from even entering your 
system.

Header checks are expensive in postfix but not as much having to run the 
whole message through MailScanner, spamassassin, ....

So I would advise anyone to become really good with customizing your MTA. 
MailScanner is a great tool. But any SPAM I can stop from completing it's 
SMTP connection saves me bandwidth and other resources.

Can we add that slogan to the website?
 	Treasure your MTA. It's MailScanners best friend.

Right. Where were?
