Because the only imap server that'll serve old-fashioned single-file mail 
folders is wu-imapd, which is a) buggy as hell, b), slow as hell, and c) 
slows things to a crawl on the server it's running on. The other imap servers 
out there require Maildir-format mail folders, which chew up your inodes like 
crazy and thus aren't suitable for an ISP's mail server.

Since I run my own mail server and only have five or six people using it, I 
can run imap on it. But it does get very slow when dealing with messages with 
large attachments, or with very large folders.
