The End of (SMTP) Innocence

The End of (SMTP) Innocence David Reed writes about how Spammers and the ISPs trying to block them are making SMTP mail usage impossible. I've hit the same problem using VoiceStream's GPRS service for my handheld: they block Port 25, which is used by my Pocket PC for sending email. So I can't send email over their Internet service unless I use a special web page -- and here I was thinking we developed "email clients" for a reason (otherwise everyone would be using Hotmail, not Outlook.) I can't imagine anyone using their service for spamming, considering it runs at about half the speed of a modem. Administrator mentality run amok -- they'll make everyone miserable rather than find a better way to block a small minority of offenders.
