Restrict/Prevent POP/IMAP Access by Hotmail Yahoo etc

We would like to prevent users from pulling their email
off our pop/imap server through Hotmail, Yahoo etc. The
obvious solution is to set up a firewall rule to prevent
access by Hotmail, Yahoo etc servers.

Has anyone addressed this problem?
Has anyone compiled (sells?) a list of IPs to block?
Is there a better way to address this problem?
(Yes I know about SSL, that's on my list-of-things-to-do,
and SSH isn't an option for my user base).

Rgds to all,
TIA,
I will summarize...
