That's precisely the reason why Sendmail exists.  Why do you have to use
"something else"?  It should be relatively painless to set up Sendmail
to accept incoming email from a specific set of hosts/addresses using
any method you find more convenient:

  * Firewall rules which block access to port *:smtp from hosts which
    should not be able to access it.

  * /etc/hosts.deny controls

  * The /etc/mail/access file of Sendmail itself.
