Here are some upgrade paths: 1. add another pair of mirrored drives, and move your mailboxes to that, leaving the other pair for mailqueue. this double your disk bandwidth, a huge gain. 2. add imgate out front. a. this will reject 15% to 30% of your incoming mail as junk or abuse (2000 to 4000 msgs less to Imail). Then you could remove declude junkmail since it would be scanning "cleaned" mail to catch the crumbs but at a high processing expense. b. IMGate will take over send/receive of mail with slow internet, and Imail will send/receive mail with very fast IMGate, meaning IMail will have fewer SMTP-/SMTPD processes in memory than now, and no DNS lookups. c. have the users send their outbound through imgate using pop-before-smtp, removing 300 mb of outbound traffic from IMail. You're Imail server will be much zippier and more reliable. Len Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
