RE: sendmail works only for localhost

Thank you for the suggestion about the DAEMON_OPTIONS. Now it listens on all 
interfaces and even sends mail to external hosts.
However I seem to have broken something for local mail delivery is not 
working. Here is the output in /var/log/mail.log

EX_TEMPFAIL

And it is not listening on POP3 port for clients to connect and fetch mail.

I am kind of confused with these MUA, MDA, MTA. IF sendmail is the MTA, what 
will the MDA in my case be.

Thank you again for the help provided.
And I am posting rather late but there is time zone difference and it is late 
at night when you answered.
