Sendmail not rewriting the domain of the sender.

I have the following lines in my sendmail.mc file:

FEATURE('always_add_domain')dnl
FEATURE('masquerade_entire_domain')dnl
FEATURE('masquerade_envelope')dnl
FEATURE('allmasquerade')dnl
MASQUERADE_AS(`domain.org')dnl
MASQUERADE_DOMAIN('domain.org')dnl

This should perform the following 

	me@xxxxxxxxxxxxxxx  -> me@xxxxxxxxxx 

It is, as of now, leaving the address as

	me@xxxxxxxxxxxxxxx

I've run 

	/etc/init.d/sendmail restart 

after making the changes, with the same results. Is 
there another option I'm missing here?
