Bad idea! Think about all those hosts listed in a RBL and the users canīt
do anything about it? Especially dailup/dsl users with dynamic IPīs. So,
I see a warning that my IP is blacklisted because of some idiot spamming
around with my current IP hours ago?

A working solution (practiced at the TU Graz / Austria) would be an open
mail relay for every user in the ISPs address space and block all outgoing
connections to port 25. The users will be forced to use the ISPs relay and
canīt send out virii/[apply your favorite filter rule here] etc...

My 2 cents ;)
