Mario,

I think your problem is that the remote SMTP daemon is shutting down the 
connection, possibly based upon the source IP.

"Connection closed by foreign host" means that the remote server shut you down 
for its own reasons.

Typically you get a "220" status message, including the SMTP daemon version 
information, immediately after the "Escape character is '^]'" message.  Since 
you aren't getting that then it is safe to assume that the remote doesn't 
want to talk with you.

Contact the remote.
