Well, no. Adding to already disk-starved systems the additional overhead of network file access is to be strongly avoided unless you have architected a SAN through which you can get competitive performance (generally at quite a cost). Since POP, IMAP, and IWEBMSG all read from the same message store, simply relocating that store over the network will not give you an effective distribution of resources, even theoretically. To get optimal performance for mailbox-server-only tasks--local message delivery, local message retrieval, and web-based message submission--the goal is to dedicate as many disk spindles as possible to these tasks, and take any other tasks off the box. Thus, a much simpler architecture is: Server A: IMail mailbox server (POP, IMAP, WEB, SMTP)...and all the disks, RAM, and CPUs you would've put in the third server! Server B: MX and outbound gateway (SMTP only) Enabling Server B to perform SMTP AUTH, if possible, is key to getting all non-essential tasks off the mailbox server (which has no reason to make any remote connections). -Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] ------------------------------------ To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
