    Sendmail refuses all connections except localhost

    Hi all,

    I've just installed sendmail and it works fine if i telnet to it like so:

    telnet localhost 25

    I can communicate with the daemon and get my email queue'd for delivery. The private network IP running the server is and when i do this

    telnet 25

    whether its on the actual server computer or a computer on the private network the connection is always refused. Any ideas?

    This could be a firewalling problem - check that the firewall settings on your system allow connections over the lan on port 25.

    Sendmail is configured that way by default. Comment out the "DAEMON_OPTIONS(`Port=smtp,Addr=, Name=MTA')dnl" line in, rebuild your and restart the sendmail daemon.
