I run a SmarterMail server, and have blocked a few IPs, very selectively, only after I notice that consistent spam comes from those IPs that Barracuda or the other RBLs do not catch. No complaints from clients so far. I don't block entire countries or regions, though I have heard of administrators who do so. Some of my clients travel a lot, so I don't block countries.
I send out friendly reminders to my clients to teach them how to recognize spam and use spam filters in MS Outlook. I hope at least a few people read them. =) Perhaps you can have a conversation with your hosting provider about using RBLs and configuring a firewall to do the spam blocking that he needs.
