Do not take it offending, but you should only run a mail server public
reachable after you learned the basics.

If you would have a look at the original sendmail.mc file shipping with
FC1 you would see:

dnl # PLAIN is the preferred plaintext authentication method and used by
dnl # Mozilla Mail and Evolution, though Outlook Express and other MUAs
do
dnl # use LOGIN. Other mechanisms should be used if the connection is
not
dnl # guaranteed secure.
dnl #
dnl TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
dnl define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5
LOGIN PLAIN')dnl

MECH means the mechanism SASL uses to handle authentification data
(username and password). And the saslauthd is the SASL authentification
daemon, run by the init script /etc/init.d/saslauthd.

You domain name is not listed in the /etc/mail/local-host-names files.
