Thanks for the help.
Ironically, I have done something similar under /etc/sendmail.cf.
I added:
Cwbawel.net
Cwpioneer.bawel.net
(I am not sure which one is important, so I did both).
Yet, after I added the two lines or the /etc/sendmail.cw, nothing changed!
I thought I did restart sendmail daemon by using kill -HUP.
Apparently kill -HUP didn't force sendmail daemon to re-read sendmail.cf.
So, I had to kill -9 and restarted sendmail with /usr/sbin/sendmail -bd .
Now, emails to user@mydomain works!
Just a little note. Beside adding the MX record:
my.domain IN MX 0 hostname.my.domain
"DNS and BIND" also suggests to add:
my.domain IN A xx.xx.xx.xx (where xx=IP address of the host)
I don't know what the use for the additional A record other than it lets me
telnet to my freeBSD box without specifying the hostname.
