Get "the original sendmail distribution, unpack and identify
the .mc repository. See if your m4 will build .cf from one
of the .mc files, if not, sh Build to build your own modern sendmail.
( it's not that complicated and you will have a full version in the
process)

You might not need to change your sendmail binary, you _could_
use the sendmail distribution just to "create" your sendmail.cf.

Given enough interest, i show an example of how FreeBSD
organized their sendmail :

/etc/mail contains what's needed create your sendmail.cf,
in addition it has a Makefile that governs all phases of
thsi process.

Here is a ls -l from one machine :
> cd /etc/mail
> ll

-rw-r--r-- 1 root wheel 6570 Apr 3 2003 Makefile
-rw-r--r-- 1 root wheel 2899 Apr 3 2003 README

-r--r--r-- 1 root wheel 38840 Sep 19 2003 submit.cf
-rw-r--r-- 1 root wheel 573 Apr 3 2003 virtusertable.sample

Note the nyheter.ipsec.se.mc ( the machine is named "nyheter.ipsec.se")

Typing a single 'make' is all that is needed to regenerate
aliases, access and any usertables, in addition to .mc to
.cf generation. Lets do an example of this :
( i'll touch the .mc file to simulate an edit )
# touch nyheter.ipsec.se.mc
# make
/usr/bin/m4 -D_CF_DIR_=/usr/share/sendmail/cf/ /usr/share/sendmail/cf/m4/cf.m4 nyheter.ipsec.se.mc > nyheter.ipsec.se.cf
#

great we have a new .cf file :
# ll nyhe*
-rw-r--r-- 1 root wheel 57023 Apr 28 00:17 nyheter.ipsec.se.cf
-rw-r--r-- 1 root wheel 4172 Apr 28 00:17 nyheter.ipsec.se.mc
#
The file needs to be renamed to "sendmail.cf" which is what sendmail
expects :
# make install
install -m 444 nyheter.ipsec.se.cf /etc/mail/sendmail.cf
install -m 444 freebsd.submit.cf /etc/mail/submit.cf
#

We need to restart sendmail , lets do it:
# make restart
Restarting: sendmail sendmail-clientmqueue.
#

And we are done, the bottom line of maillog shows :
Apr 28 00:19:18 nyheter sm-mta[95]: restarting /usr/sbin/sendmail due to signal
Apr 28 00:19:18 nyheter sm-msp-queue[98]: restarting /usr/sbin/sendmail due to signal
Apr 28 00:19:18 nyheter sm-mta[98730]: starting daemon (8.12.10): SMTP+queueing@00:30:00
Apr 28 00:19:18 nyheter sm-msp-queue[98732]: starting daemon (8.12.10): queueing@00:30:00

The whole process is thus controlled by a makefile and all
commands needed is summarized as :
make
make install
make restart

You could use a FreeBSD system to generate sendmail.cf for your
current system ( while porting the above Makefile)
