This document covers some fundamental concepts for consideration when setting up or configuring a mail server.
Disk IO Subsystem
Note: The primary consideration in hosting any mail server is disk IO - as all mail servers can be very disk IO intensive when placed under load. Consider SCSI, SERIAL ATA or the fastest hard drives available if hosting large numbers of mailboxes.
Also keep operating system and page file on different physical disks; and consider RAID on mail file storage. Again - these guidelines should apply irrespective of which mail server is used.
Need to minimise the size of mailboxes where possible. Server hosted mailboxes over 5GB can cause significant disk IO.
Do not use catch-all mailboxes unless they are monitored and purged periodically.
At a minimum, keep daily backups of the Mail Enable\Config directory. This directory is not large, but contains all the information regarding domains, address maps, user logon information, etc.
