Re: Problem with port 25 in HP-UX 10.20

Are you running sendmail on the server?

If so, you might generate this error by attempting to telnet in. However you should actually see your mail system prompt you for information.

If sendmail is not running as a daemon then you should get "unable to connect"

See if the /etc/services file has correct information in it, perhaps compare it to another server that is working properly.

It sounds like your sendmail.cf file is corrupted or badlt misconfigured. You can rename the current /etc/mail/sendmail.cf to something.old and copy a clean version from newconfig:

cd /etc/mail
mv sendmail.cf sendmail.cf.old
cp /usr/newconfig/etc/mail/sendmail.cf sendmail.cf

Now telnet to port 25 should work OK. Note that you still need to make changes to your sendmail.cf file to get email working.
