>Spliting up IMail modules to run on different machines, one for smtp and >one for web messaging?
Great idea... but you can't do it with IMail modules. I use FreeBSD and Qmail. Others prefer PostFix and they're probably right. So, yes, go ahead and bring up a machine for SMTP traffic. Point the high-priority MX records to it. Tell it how to route SMTP so that the POP3/WebMessaging box(es) are the final destination. You can use it for your outgoing gateway, too. Then put your antivirus and anti-spam goodies on the Unix box. Len has perfected this system with IMgate. I cobbled one together for very little money and time before I met Len, too. It's a worthwhile project. My set up with FreeBSD/Qmail/qmail-scanner/Sophos/spamassassin has been 100% effective in blocking viruses, more than 90% effective in identifying SPAM, and processes around 10,000 messages an hour with very little (as in no) backlog. But do consider IMgate as a more evolved and polished solution. Good luck, Mike Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
