That averages to 16,666 mail messages per minute or about 500 per minute per server. The best part was the servers weren't breaking a sweat. Again as with all benchmarks you are talking about, there are lots of other factors then just "How fast does it push the mail." For what we do, qmail is a great solution. I've personally never looked at postfix, but I understand it to be a great MTA as well. I think in the end, you will find that both are very similar and that it's just a matter of personal preference. That being said, I'll be interested to see what the numbers come out to be. -gordon On Mon, 19 Feb 2001, Dan Phoenix wrote: > I would like to set up this challenge early next week. > NOw that I have taken out the IO issue with the mail servers > ...already proved postfix did better on I/O so now i want to eliminate > that factor to 2 exactly the same machines.
