What's wrong with port 587 (rfc 2476 sec. 3.1) and requiring SMTP AUTH
(rfc 2554), as people have widely deployed today?  The problem is

It'd be really nice is mail client programs had an easy way for users to configure these settings. We have to walk our clients through the advanced settings in Outlook Express, Eudora, and other programs often.
