Based on cyrus documentation, imap server need up to 512 K RAM per 
connection.  Assuming 5 connection per user (mozilla default), it is up 
to 2.5Mb per user, so with 32Mb Ram and only apache2/mail server running 
I should be able to support up to 4 users without any problems.

Is anyone running cyrus on low memory computer? Any thoughts on this issue?
