jcurran () mail com:
You block port 25 until a customer says that they're claim to have
setup a responsible mail submission agent and demonstrate the
necessary clue density.

Then in all fairness block also port 80. A comparable amount of junk
is sent using port 80.

This can be readily determined by having customer support mail
a short form with relevant questions such as "Is your mail server
RFC2505 compliant?", "Please list the mechanism used to secure
mail submission to your server?", and "Are you prepared to handle
SPAM reports for all email originated or relayed?"   No problem for
someone who knows what they're doing but enough to deter the
random end user.

Ditto  | sed  -e 's/25/80/' -e 's/SMTP/HTTP/' -e 's/MIME/HTML/'
