First off, disable the network checks and move any RBL checks you relied on SA for out onto your Internet-frontend SMTP server. That way you lose no functionality, but remove a bunch of "hangs" from SA - which lead to loading issues. The DNS checks cannot be underestimated. We run Qmail-Scanner on all our e-mails - and it's a perl script. It typically processes an e-mail in <0.3 secs, but calling spamc adds 2-8sec to it due to all the RBL lookups going on. [I prefer running them via SA and will do so until the load gets too much - then I will take my own advice and move RBL back out to where it was designed for ;-)] -- Cheers Jason Haar Information Security Manager, Trimble Navigation Ltd.
