Any ISP worth their salt *should* block port 25 outgoing, and require 
clients to send mail through the ISP's relay.  Mainly to prevent 
Microsoft Outlook being used as a viral proliferator.  There's also the 
advantage of having a virus scanner being run over your mail inbound and 

I'm of split minds as to whether it would be reasonable to expect the 
ISP to poke holes in their firewall for clients who ask.  After all - 
all it takes is for one virus to get into your only Windows box, and 
you've just become part of the problem.

If you're concerned about other people snooping on your email as it 
passes through the ISP's relay, use encryption.
