Yeah, I threw it in as an afterthought. ISP firewalls do exist and not 
just small isolated incidents. I wish more money had gone into making 
them much more adaptive, then you could enjoy your tcp/25 and possibly 
not have a problem unless your traffic patterns drew concerns and caused 
an adaptive filter to block it (eh? thousands of emails suddenly to a 
variety of servers? block). Interestingly, adaptive filters are often 
used for probing scans (and we didn't apply them to tcp/25, why?)
