The List has returned!

Heh, m4...

Have you tried Postfix or Exim? What's the biggest load you've had in 
terms of load avg, queue size etc? What kind of machines have you run 
Sendmail on?

I can tell you first hand that Sendmail does not handle being slammed 
like Postfix does. I've seen Ultra 2s (circa 97-98 SPARCs) running 
Sendmail get slammed with tens of thousands of messages at once, and 
it's not pretty.

I've seen old versions of Netscape Mail server (3.x), Sendmail, Postfix, 
Exim, and a custom MTA written and run by a very large well-known free 
E-mail site owned by another very large well-known software company that 
starts with an M, and I can tell you that Sendmail is probably 2nd to 
last on that list in terms of performance.
