>I want to open a new port (2525) and forward all packets from 2525 to 25 >so, they can use mail. try to fit into "well known ports/services", where port 587 is the "mail submission service" (SMTP client/MUA submitting to an MTA for relay/injection into the SMTP network of MTAs). Many think that all mail submitted to port 587 should require authentication. Just have your MTA listen on port 25 and port 587, keep the firewall out of the picture. Port 25 is the mail relay port (MTA relays to MTA), ab/used as the mail submission port.
