Assuming the MTA doesn't tell you (I think most of them do), you can do something like: $ sudo lsof -i :25 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME master 2134 root 11u IPv4 5054 TCP *:smtp (LISTEN) smtpd 21230 postfix 6u IPv4 5054 TCP *:smtp (LISTEN) smtpd 21231 postfix 6u IPv4 5054 TCP *:smtp (LISTEN) [...] and find out what process is listening on port 25, in this case, postfix. -- Randomly Selected Tagline: Don't marry a girl whose father calls her princess.
