Subject: FD should block attachments

First, Aunt Tillie ought not to be sending files around the Internet, 
IMHO. But we've already lost *that* battle, so ...

Basically, attachments in SMTP sux0r. File Transfer Protocol (which no 
one should use since it's insecure) was designed for ... transferring 
files. SMTP was not - go ask Eric Allman, he'll know. However other 
protocols will do (HTTP works, although blocking sux0rz). SSH comes to 
mind (unless Microsoft has co-opted *that* too).

Why not help Aunt Tillie install WinSCP? No more need for server access or
perms or disk quotas (cuz it goes from her craptacular Winbloz box to 
someone elses' craptacular Winbloz box) *and* it's secure (or as secure 
as anything running on a Winbloz box can be these days).

If we list members are as Godlike as we pretend to be we'd declare a 
national holiday and send out one final SMTP attachment to wall the Aunt 
Tillies (and Uncle Leos) of the world with WinSCP and a link to some nice,
clear, screen-shot-laden instructions on how to install and configure it.

Oh, of course they'll all need static IPs, which will make beaucoup $$$ 
for decent ISPs and will help get rid of crappy dynamic PPPoE DSL and
dial-up providers thank heaven. Another nice side benefit, the RIAA can go
hang trying to catch all the *secure* file transfers of mp3 ph1l3z

Now someone go write a GPL WinSSHD so that they'll be able to *receive* 
the miserable ph1l3z they'll spew back and forth 8-)
