Sounds like you need a Postfix relay/gateway.  That would certainly offload a lot of SMTP traffic to the Postfix machine, and if you find you get a ton of deferrals you can setup another Postfix machine to only handle deferred mail.  Len has information on his site to immediately get started using FreeBSD or you can check out the documentation that is coming for RedHat 7.1 on www.postfixgate.com when it is available.

Subject: [IMail Forum] Windows 2000 better than NT for IMail?

Hi,
I am looking for general information as I know one would need more info to judge my situation. I am in the thinking stages now and could use some input.
 
I have a NT server 800 MHz, 256 MB RAM and am running IMail with about 8000 users. These are very very heavy users (Most are on several mailing list, etc) and my number of users increase every day for about 20+. I am having problems with system crashes. I am more of a Unix person and not used to using Windows for email.
 
Could I be better off using Windows 2000? Should my NT system be able to handle the load as it is now?
 
Any comments would be helpful.
 
Thank you for your time,
Vincent
