sendmail IP
when you nmap localhost, you are nmapping the IP 127.0.0.1 and you see that sendmail is listening on port 25
when you nmap from elsewhere, you are investigating a different IP e.g. 192.168.0.3 and sendmail is not listening on port 25 of this IP if you go have a look in your sendmail.mc file for the line DAEMON_OPTIONS you'll see 127.0.0.1 and you'll be able to change it for the machine's other IP... i expect you want to use this machine to relay messages for the rest of your network? you'll also need to put RELAY lines in your access.db file [see FEATURE(access_db...etc in the sendmail.mc]
