     On our servers here are some sendmail.mc lines referring to our domain.
 May be they will help.  These are from our main server:

define(`confDOMAIN_NAME',vigyan.com)dnl
CLIENT_OPTIONS(`Family=inet,Addr=vigyan.com')dnl
define(`SMART_HOST',`vigyan.com')dnl
FEATURE(`smart_host_domain',`vigyan.com ')dnl

These are from our slave servers:

CLIENT_OPTIONS(`Family=inet,Addr=slave.vigyan.com')dnl
MASQUERADE_AS(vigyan.com)dnl
MASQUERADE_DOMAIN(vigyan.com)dnl
FEATURE(`allmasquerade')dnl
FEATURE(`masquerade_entire_domain')dnl

FEATURE(`smart_host_domain',`vigyan.com ')dnl


Make sure you have sendmail-cf RPM installed also. I normally do the
fixes by hand as in

DATE=$(date -Im)
yum install sendmail-cf
m4 < /etc/mail/sendmail.mc > /etc/mail/sendmail.cf.${DATE}
diff /etc/mail/sendmail.cf /etc/mail/sendmail.cf.${DATE}
cp -b /etc/mail/sendmail.cf.${DATE} /etc/mail/sendmail.cf
service sendmail restart
