Well, for some reason it seems that the remote server is never sending the
DATA command (which is what is used to actually pass the email message to
your server).
You could use ethereal (www.ethereal.com) to capture all traffic coming in
(just make sure you put a filter on it, so you're only capturing data on
port 25!)
Cheers
