        http://www.sendmail.org/~ca/email/auth.html      (SASL)
        http://www.sendmail.org/~ca/email/starttls.html  (TLS)

(SASL authentication is probably more work than TLS authentication.
TLS is compiled in on -current and anything that has sendmail 8.11.6
or higher.)

As an aside, TLS is cool.  Even without any pre-shared keys it will
encrypt the channel between two similar sendmails.
