Mailscanner / Postfix / Procmail

[Patrick Healy]

Hi,

I know this is going to sound like a newbie question, but I'm having a 
brain hiccup and can't seem to completely wrap my head around this...

I'm relatively new to postfix, but I've got a MailScanner / Postfix 
configuration set up and working.  Traditionally I would have set up a 
procmail rule to handle the spamscore and dump SPAM in to a folder.  
However, I'm seeing notes about the huge performance hit that I'll take 
if I enable procmail in the postfix/main.cf file.

My question is this - should I be using procmail to filter the SPAM that 
MailScanner/Spamassassin tag?  I know that MailScanner is taking things 
out of the HOLD queue and tagging them, then replacing them back into 
the incoming queue for Postfix to deal with, but I figured that 
MailScanner would handle the SPAM between those two steps so as not to 
add to Postfix's load...

Any thoughts?

Thanks to all!

Pat
