Paul&David,

Not all users have luxuriy of having SMTP server doing authentication on 
port 587 (plus, some ISP might block that one too).  Plus you need 
support in mail client to connect to port other than 25 (not all support 
it).

Webmail is nice, but not all people like it.  It is especially 
inconvinient for people who use POP3 to get their mail.  Again, in this 
hypothetical situation, you are forcing legitimate sender's to deal with 
your spam problem (just like with TDMA, maybe even a bit worse).
