I don't want to start a flame war, but you might try exim + greylisting 
rather than sendmail + greylisting. If your configuration isn't too 
complicated, setup is easy enough even without any exim experience you can 
give it a try and see if you like it. There will be a learning curve since 
the exim config file is very different (but nicer IMO) than sendmails.

Exim handles heavy load pretty well and has config directives that allow you 
to set different behaviors (like queue mail only) when the load level exceeds 
a maximum.

On the other hand, I can't even convince my own brother to switch. Hes got 
something like 20 years experience with sendmail and isn't going to look at 
anything else even if someone holds a gun to his head.

Oh well.
