Yes, and some of you thanked us for blocking RPC in the ISP or in the 
cable modems. Many such blocks are still in place in many ISPs as there 
was no reason to ever remove them. TCP/25 outbound is often blocked in 
many locations as well. Just because you don't notice the firewall, 
doesn't mean it doesn't exist. We stay in business when you don't notice. :)
