Adding WorkAroundBrokenAAAA seems a necessity even in the submit.mc given
the number of broken DNS servers out there in the world. Since we are
diverging from the sendmail.org submit.mc, it's time to make our own
freebsd.submit.mc.

Non-sendmail users use the FreeBSD sendmail startup functionality to start
alternative MTAs. Therefore, always install rc.sendmail, regardless of
NO_SENDMAIL make.conf setting. Users can still set mta_start_script to a
different script.

Provide a new make.conf knob, SENDMAIL_SUBMIT_MC to allow users to pick

Quoting Peter Wemm, "At great personal risk, touch the sendmail startup
again."

As an alternative to sendmail_enable=NONE, solve the boot time problem
for non-sendmail users completely by moving all of the sendmail startup
code from /etc/rc to /etc/rc.sendmail. The source for that script will
be kept in src/etc/sendmail/rc.sendmail so make.conf's NO_SENDMAIL will
prevent it from being installed. A new rc.conf variable,
mta_start_script specifies the script to run to start the user's
preferred MTA. For backward compatibility, it will default to
/etc/rc.sendmail. The specified script is called out of /etc/rc after
checking to make sure it exists. A new rc.sendmail.8 man page has also
been added which now houses the sendmail_* variable descriptions
formerly in rc.conf.5.

Use /etc/rc.sendmail in /etc/mail/Makefile to reduce code duplication.

Add new build knob, SENDMAIL_SET_USER_ID, which installs sendmail as a

Therefore, we shouldn't install /etc/mail/submit.cf if it is set.

Since buildworld builds cf files specified in SENDMAIL_ADDITIONAL_MC,
installworld should install them.

Add a new make knob, SENDMAIL_MC, which is meant to replace SENDMAIL_CF as
users should be configuring via m4 now. If set, use m4 to create the .cf
file. Also, if either SENDMAIL_MC or SENDMAIL_CF is set, 'make install' or
'make distribution' in src/etc/sendmail/ will install the appropriate .cf as
/etc/mail/sendmail.cf. This fixes some mergemaster problems.

Move creation of the sendmail statistics file from the usr.sbin/sendmail

Install sendmail.cf into /etc/mail.

The current offical Sendmail Inc. version uses /var/mail/ and when we upgrade
