Hi guys. I've been playing around with Linux lightly for about a year now. Just installing Ubuntu to use as my new mail server following this tut http://www.howtoforge.com/perfect-server-ubuntu8.04-lts However, when i get to checking the response of SMTP i am not getting a response. When i telnet in (telnet localhost 25) i just get Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. No 220 response, even when i type in a ehlo command. It works fine on port 110 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. +OK Dovecot ready. This is the only info i get on a netstat of smtp root@mailserver:~# netstat -l | grep smtp tcp 0 0 *:smtp *:* LISTEN tcp6 0 0 [::]:smtp [::]:* LISTEN unix 2 [ ACC ] STREAM LISTENING 18460 private/smtp unix 2 [ ACC ] STREAM LISTENING 18516 private/bsmtp root@mailserver:~# I have seen plenty of problems with this around the forums but nothing that looks like it could fix mine. I have gone through my 'main.cf' and 'master.cf' and it looks as it should. I can post if it helps. Thanks guys.
After a day working on it and it not working, it appears that 5 minutes after posting this i got it working. I must have the main.cf file wrong as i copied one straight from a working machine and changed the needed details and yay.... Here is the file i used for future reference # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.
