Hardware Requirements

The table below estimates the hardware requirements per number of users:

Users	Processor	Memory
2000	Intel P3/500	256 MB
5000	Intel P3/700	512 MB
10,000	Intel P3/1.1	512 MB
25,000	Intel P4/1.7	1 GB
50,000+	Intel P4/2.6	1 GB

This table assumes that basic mail services (eg. POP and SMTP) are used only. Other services (like IMAP and web mail) are more resource intensive and as such are likely to require more infrastructure. It is also important to realise that other services and configurations will significantly adjust these estimates. It is important to recognise that the Disk I/O subsystem is a major consideration when the mail server is placed under load. Also, for large implementations, high speed drives (15K RPM) are recommended, as well as consideration for an appropriate RAID configuration (RAID5 is recommended).
