I just did some SMPT talking on your server. There is nothing that should 
prevent this, because there is no difference in me doing some SMTP talking or 
the first mailserver doing the same stuff.

Now about the from: mailer-daemon question. I simply entered an empty e-mail 
address (from:<>) and most mailer daemons replace that by some default. That 
is expected behaviour.

Next to know is that you can never,never rely on the from: address because 
everyone can configure it in his own mail client. Just try it yourself if you 
don't believe me Just change your from: address in gates at microsoft.com and 
send yourself an e-mail.

P.s. I rather copy this mail to the mailinglist as this discussion could help 
other people. Ok by you?
