port 25 does not stay open, closes after a few minutes.

Original problem, I could not get port 25 open.
But now it opens but then closes after a few mins.

I was able to open port 25 by modifying the sendmail.mc
Find this line in /etc/mail/sendmail.mc:

DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')

and change it to:

DAEMON_OPTIONS(`Port=smtp, Name=MTA')

The default setting restricts sendmail to accepting connections only from
the same host, for security; now it will accept connections from elsewhere.



But now port 25 only stays open after a few mins and then closes and stays
closed.

Help Please.

Thank you everyone.

Does sendmail report any problems in the log file?

This is a short copy of the /var/log/message file.

As soon as I enable the sendmail service port 25 is immediately taken by
another application.

Re: port 25 does not stay open, closes after a few minutes.

It sounds as if you have other sendmail processes running. What I would do
is this:

First, kill all sendmail processes:

killall -9 sendmail

Then if you want sendmail to listen on "all" interfaces I would set the
following in your sendmail.mc

DAEMON_OPTIONS(`Port=smtp,Addr=0.0.0.0, Name=MTA')

Then I would rebuild your sendmail config.

Alternately, I would check to make sure that nothing else is attempting to
run on port 25 (postfix?)

netstat -tunap | grep :25

Try that and see how it goes.
