I have a RubyOnRails application running on the same server that runs sendmail. The application sends out (no need to receive) emails via the local sendmail.
Now I intend to move sendmail to a dedicated server. How do I make sendmail on that server accept connections from my application on the other server?
I modified sendmail.mc from
DAEMON_OPTIONS(`Family=inet, Name=MTA-v4, Port=smtp, Addr=127.0.0.1')dnl
DAEMON_OPTIONS(`Family=inet, Name=MTA-v4, Port=smtp')dnl
I have also added to /etc/mail/access:
m4 sendmail.mc > sendmail.cf
and restarted sendmail.
Trying to connect from my app server with telnet on port 25 to the mail server gives me:
telnet: Unable to connect to remote host: Connection refused
Am I missing something?
