What do you mean by that?Are you talking about the TCP connection originating from port 25? Or something else?
Also, why not?
mails there is final recipient only, not forwared
I disagree.I see people forward old university email (comes into university system on port 25) to somewhere else (again port 25), which is then forwarded a 2nd time to the final destination (again port 25).
