Exchange 2000 SMTP is quite good, providing you don't skimp on hardware. I have a couple of Exchange SMTP gateways that are load-balanced with WLBS. One is a dual CPU, 650MHz, 512 MB RAM. The other one is single CPU, 800MHz, 512 MB RAM.
They are probably relaying ~50,000 messages per day and do not seem to be stressed. I like Exchange 2000 as SMTP relay because the queue management is pretty nice. I would not recommend using IPSwitch Imail as an SMTP gateway - it chokes when it has to send a lot of mail at once. Rockliffe Mailsite is pretty good. It also has aliasing capability. For example you could create a wildcard alias *@company.com -> *@exchange.company.com and it will rewrite the addresses and reroute mail. However I have also seen MailSite choke on large amounts of mail. And queue management is not that untuitive. -----Original Message----- From: Pfefferkorn, Pete (PFEFFEPE) [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 25, 2002 1:40 PM To: Exchange Discussions Subject: IMC as relay system (off topic) Exchange 5.5 SP4. Sorry to post this again. Maybe someone new has some information. Well the system that processes the @UC.EDU aliases for the University finally took a big hit. Its a VMS system running PMDF and is run in a different department. We've been asked to look at alternative replacement systems. The system is processing about 40,000 inbound messages a day. I really like the Exchange IMC since it's menu driven and I have monitors in place that can page when something happens. Also it does some validation work, such as SMTP address already used and so forth. Couple of questions. 1) Is anyone else shoving 40,000+ inbound messages through an IMC? We would have a dedicated box for this function in the existing site and would only be used for inbound messages destined for @UC.EDU. It would also route messages to other e-mail systems such as our student POP/Unix based messaging system for those users whos alias points to an alternate system. 2) Is there some other 3rd party product that is user friendly (versus text updates) that might be a good replacement that anyone might want to recommend? 3) We could go with a Linux system with an SMTP mailer. We do have a administrator on staff here that runs the POP system and a Linux deployment was mention. I don't like the fact that its line based and additions are not immediate and require recompiling (maybe don't have that term right). Thanks!
