    Please don't suggest such things, even in jest! I am in the process
    of switching ISPs right now because the geniuses at mine decided that they
    would rather block port 25 in *both* directions at the border than deal
    with abusers properly.

    For those that would ask "what harm does using the ISP's mail server cause you
    if you are not a spammer?", go read RFC 2487. For one of my mail accounts,
    I connect directly to a particular mail server, then use the STARTTLS
    extension along with mutually authenticated SSL, and that is the only way
    I can send mail to certain non-public mailing lists.

    Why not just make the only commercially available "internet access" go through
    their ISP's http proxy? Anyone who wants to send mail can use webmail,
    and anyone who wants encryption is probably evil anyway.

    Regards,
    petard
