You are doing a new install, or have erased /etc/mail/sendmail.mc.
If you've accidentaly erased /etc/mail/sendmail.mc, check /var/backups.
I am creating a safe, default sendmail.mc for you and you can
run sendmailconfig later if you need to change the defaults.

*** *** *** WARNING *** WARNING *** WARNING *** WARNING *** *** ***
Everything you need to support STARTTLS (encrypted mail transmission
and user authentication via certificates) is installed and configured
but is *NOT* being used.
To enable sendmail to use STARTTLS, you need to:
1) Add this line to /etc/mail/sendmail.mc and optionally
to /etc/mail/submit.mc:
include(`/etc/mail/tls/starttls.m4')dnl
2) Run sendmailconfig
3) Restart sendmail
Updating /etc/hosts.allow, adding "sendmail: all".
Please edit /etc/hosts.allow and check the rules location to
make sure your security measures have not been overridden -
it is common to move the sendmail:all line to the *end* of
the file, so your more selective rules take precedence.
