Or embrace the concept of IMAP =) The fact that you do not loose your mail when your disk gets lost is a very good reason to use IMAP - that is if you backup your server. Also, you can provide offsite access to mails via webmail and / or imap as well as provide your users with shared folders (something mine loved). > 1.

How many users do you have? 50, 100, 10 000? > 2. What is considered a reasonable quota (I know this is a very broad > question)?

My users have a quota of 2 gb (2x gmail) on one site and 100 mb on another (with a select few having a quota of 500 mb). Cyrus does not have a problem with this. Reasonable quotas is something that IMHO is a function of your budget. It is better to keep users mail on the server that have them keep the mail localy.
