Sendmail - problem creating SMTP socket 2

[hellsing]

I think I have a conflict on port 25. I have sendmail running which I know listens on port 25 but whenever I try to email to an external email addres I get the following in /usr/adm/syslog

Dec 19 16:37:05 rocc2 sendmail[9888]: NOQUEUE: SYSERR(root): opendaemonsocket:
aemon Daemon0: cannot bind: Address already in use
Dec 19 16:37:05 rocc2 sendmail[9888]: daemon Daemon0: problem creating SMTP socket

I think possibly there might be something else using the same port. Does anyone else agree. Also if this might be the case how do I check to see if anything else is using this port.

I have the following in the config file:

# "Smart" relay host (may be null)
DSmail.domain.co.uk

Should I use the IP address instead?

I have my relay host setup with an ip address of my mailserver and it works fine. It's worth a shot.

You shouldn't be using "sendmail" to send the mail. You should be using "mail". "sendmail" is a daemon that runs in the background and processes the mail, it's not supposed to be a front-end.

If you have mail.domain.co.uk in your /etc/hosts file you shouldn't need to use the IP address in sendmail.cf, but it doesn't hurt to try I guess.

OK I have got it working.

"joens" post on setting up sendmail to not use DNS worked a treat. As I posted I still couldn't get emails out but that was down to the mail server they were going to.

Once I configured this sendmail is happily sending emails to all and sundry now.

Thanks very much for all the help everyone.
