True... If you review the NANOG archives you'll find that at least in the case of the port 25 absurdity, I have noticed and have railed against it.
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?)
