Hello, im doing some work for a organization who has recently been
placed on several RBL's most notably was http://cbl.abuseat.org/. upon
looking
at the mail server ive noticed the following. Please tell me if this is
normal behavior for a postfix server, I only know qmail. Also the
system has a internal IP which you will see coming up, and is going
thru a PIX

Telnet session:

OK, connected to <external IP>...
