Note the connection to port 25.  I did not say to send anything on that port
to verify the domain, just open the port.  To verify that the port is not
valid for the www.example.com domain, you would need to send an email to
that domain!  Talk about spam!

No. You only need to go as far as MAIL FROM:<> and 
RCPT TO:<user(_at_)www(_dot_)example(_dot_)com>. You wouldn't need to enter the 
data
phase and actually send any mail.
