I use Qmail on almost all of our SMTP servers. On the ones that only 
house a couple hundred email addresses, your setup works flawlessly in 
our environment.

On the boxes with 10k+ email accounts, I do away with all of the 
filtering stuff, and front-end the Qmail/Vpopmail boxes with third party 

 From what I can tell, it's the filtering processes that are the 
bottleneck under heavy load. Take them out of the equation and load is 
no longer an issue.

Just my .02.
