Fedora core 1 sendmail problems

[Homer Sapions]

My sendmail.cf has
O DaemonPortOptions=Name=MTA

and /etc/mail/relay-domains has
localhost
myserver.mydomain.org
myserver2.mydomain.org
myserver3.mydomain.org

because I have Apache set up with multiple virtual hosts, and want to be 
able to receive mail at any of the registered server names. sendmail.mc also 
has
MASQUERADE_AS(`myserver.mydomain.org')dnl
to ensure that all mail appears to come from one location.
