Actually I administer several mail servers and I think that a tool like
popauth3 could be useful to fight UCE.  Perhaps you don't have a bunch
of remote users who use hotel, dialup, wireless hotspot, or other
Internet connections.  As you know mail servers have to restrict somehow
mail they accept for relaying.

If a mail server accept any old mail for relaying, then the spammers 
win.

If you restrict the relaying to a few IP addresses, then the spammers
can't use your mail server as a relay, but neither can your mobile 
users.

If you have a tool like popauth, then the spammers still can't use
the mail relay, but your mobile users can.  This is how it fights
UCE.

What about the original post makes you think it's list spam?  I took
it as an announcement of a potentially useful software tool.
