I've configured sendmail.cf file and sent a test. Failed. /var/adm/messages log file showed "Unknown Domain" error. Added my domain to the sendmail.cf file and error went away but I still don't receive messages. And now there's no errors in the log file to point to another issue.
mailx -s "This is the subject" to_me@mydomain.com < /dev/null
The log file in /var/spool/mqueue shows the message was accepted for delivery. Does this mean my relay server is holding up on my messages?

Actually it looks as though it was the mail server. I changed the relay server to another host and it worked.
