How much mail can Exchange process? A lot. If you understand how an e-mail is handled with Exchange SMTP services, you can design the server (include memory, processor and disk layout) you can make it fly.
I stress tested the IIS SMTP to see what I could get out of it. I rated the box at over 500k messages an hour before I ran out of equipment to send and receive e-mail. The gateway box wasn't stressed very hard so I don't know what the real upper limit was. I would guess somewhere in the 800k to 1m range. [1] Sendmail is overkill for 99.9% of the systems out there. Not because of speed, but because of it's complexity. With the Sendmail configuration files, I can do just about anything to an e-mail or with an e-mail that you can think of. The issue is the complexity. Most organizations don't need that kind of granularity in their configurations and want a simple potato passer for the gateway. Tell your *nix person to educate himself or have a nice warm cup... [1] I wish that Microsoft would take some of the queue utilities that Exchange gives you and allow me to add them just to IIS SMTP. Then it could be a viable gateway solution. -----Original Message----- From: Ely, Don [mailto:[EMAIL PROTECTED] Sent: Friday, December 12, 2003 9:18 AM To: Exchange Discussions Subject: RE: Mail Processing by Exchange vs. SendMail Tell him Postfix is more secure... :P Personally, I like to put another server at the edge for SMTP that is NOT Exchange when I can... As far as who's faster at processing... Who cares, can Sendmail do calendaring, public folders, etc? -----Original Message----- From: Sean Faust [mailto:[EMAIL PROTECTED] Sent: Friday, December 12, 2003 9:20 AM To: Exchange Discussions Subject: Mail Processing by Exchange vs. SendMail Good Morning All, I have a Unix/Linux admin that is just wearing me out with regards to Exchanging being 3rd rate. Given all of the variables including memory, processors, etc. How much mail traffic can Exchange process in an hour/day and what is the advantage if any of putting SendMail in front of Exchange? His last statement was that SendMail can process more mail in one minute than Exchagne can process in a day.
