First. Never use CNAMEs in MX records.
Second. Create an MX for domainname.com
Third. Add domainname.com to $w in sendmail
Fourth. HUP named and sendmail

/usr/lib/sendmail -bt 
That'll put you inside sendmail. Type a '?' at the promt.
At this point you can try stuff like /map /parse /mx /try.... 

YOu can tell sendmail what its valid local names are on the Cw line, and/or
you can tell it to get these values from a file on the Fw line.

Your mc file should have lines like the following:
FEATURE(`use_cw_file')dnl

Its all documented on sendmail.org.
