Only "trusted users" can call sendmail with the -f flag - i.e. one that
has a "T<user>" entry in the configuration file.

The "mailer" program that calls sendmail must setuid to one of the known
trusted users.  I believe effective uid is not enough - it should do a
setuid(geteuid()) if necessary.

-Jim.
