So the masquerade doesn't apply to this users, and all users defined
in the trusted-user file.

In the sendmail.cf :

# class L: names that should be delivered locally, even if we have a relay
# class E: names that should be exposed as from this host, even if we
# masquerade
# class M: domains that should be converted to $M
#CL root
CE root

In the doc :

op.txt:      trusted users from a file use Ft/file/name.

and :

confCT_FILE             Ft class        [/etc/sendmail.ct] Name of file used
                                        to get the local additions to the $=t
                                        (trusted users) class.
confTRUSTED_USERS       Ct class        [no default] Names of users to add to
                                        the list of trusted users.  This list
                                        always includes root, uucp, and daemon.
                                        See also FEATURE(use_ct_file).



So don't post from root :)
But in the aliases file add :
root:	<real user>
