Hello,

Does anyone know why Verisign has set up a fake SMTP server at
their SiteFinder service to bounce email messages sent to
misspelled or expired domain names?  The fake SiteFinder SMTP
server gives the impression that it is a real SMTP server and
happily accepts "To" and "From" email addresses before rejecting a
misdirected email message.

To and From, I'm guessing there's a database involved - oh yeah, some 
spammers from aol.com too.

I don't quite understand what technical issues Verisign is trying
to solve here with a fake server.  Any guesses?

Well, people rarely obfuscate a real envelope. Much easier that way.

I've attached an early email from Verisign that gives a bit more
information about how this fake SMTP server operates but not why it
is needed.

See above.
