|Question:||How many users can a server support?|
|Answer:||There is no hard limit programmed into the code. The practical limit is more a function of hardware and usage patterns than anything else. It really depends on the number and size of messages and attachments and the frequency with which users check their mail. In general, however, RAM is more important than CPU (since each connection calls another child process and they all reside in RAM).
With the proper equipment, we’ve seen customers operate successfully with thousands of users and hundreds of domains on a single machine.
Some of our ISPs have developed on-going user databases. They maintain those databases separately then use the data to batch edit Post.Office user information through scripts such as Perl. (See the User Guide section on Advanced User Information for details on using scripts.)
