No, no, no!  If you put

	O DaemonPortOptions=Port=smtp,Addr=127.0.0.1, Name=MTA

in the config file, the system will NOT be able to receive mail from the
outside world.  The line should read:

	O DaemonPortOptions=Port=smtp, Name=MTA

to enable reception.  The second line:

	O DaemonPortOptions=Port=587, Name=MSA, M=E

is correct if you want secure authentication.

Or add "@mydomain.com	RELAY" to /etc/mail/access.  Don't forget to
"cd /etc/mail;make" and "/etc/rc.d/init.d/sendmail restart"
