Hi everyone,

My company email server is a Linux box running @Mail software. To protect users emails in case their computer HDD's crash, we set up email accounts using IMAP and the server is backed up each night. This approach works somewhat for people with little emails (say < 1GB of emails in their Inbox), but many users have the habit of keeping everything, even spam. And over the years, their mailbox keeps being up sized whenever it gets full (instead of asking them to delete their emails). Some of the users now have more than 50GB of emails... Most users run somewhere from 5GB to 15GB... This massive amount of emails causes their email client (Outlook) to slow down alot especially when they first open it (due to all the synchronization going on between the client and the server).
So my question is, what is the email solution your company have to deal with massive amount of emails?
All inputs are appreciated.

Stanav.
