I'm interested in any studies etc. I would find TCP port 25 being blocked by my ISP to be unacceptable. It isn't the Internet anymore. The Internet's job is to shunt around IP packets, irrespective of what is in them. My anti-spam measures are so effective that I can't remember the last spam I received. I would find not be able to run my own MTA, unfortunately on a dynamically assigned IP ADSL service, as that is all I can afford, to be far more costly than the very negligable reduction in spam I would receive if TCP port 25 was blocked by ISPs.
