The problem is that you are not challanging the people who want to
send you and your users spam. While you have the right to control
mail to your users' inboxes, you do not have the right to pollute
someone else's mailbox with challanges to mail that has been spoofed.
A proper solution protects your users but does not cause inconvenience
or harm to others.

This is more annoying than those sites who send out "you sent us a virus"
messages. At least in their own misguided way, they think they are helping
other folks out. Your attitude seems to be: "I don't care who gets hurt
as long as its not me."

Have you tried greylisting? This is a pretty simple way to stop hit and
run spammers. Also, the other spam operations are picked up through sbl,
xbl and good filtering.
