No. It's actually pretty easy, depending on how you've set up your
mailserver. I'm using FreeBSD 4.6-STABLE. Rather than writing a
sendmail.cf directly, I copied /etc/mail/freebsd.mc to
/etc/mail/<myhostname>.mc and edit it to my tastes. Then it's just a matter
of cd'ing to /etc/mail and typing 'make; make install; make restart' to
generate a sendmail.cf file, copy it into place, and restart sendmail. The
advantages of this are numerous:
- Whenever FreeBSD updates some default mailsettings, incorporating them
into my configuration is just a diff-and-patch.
- Editing a .mc file is *way* easier than mucking about in `sendmail.cf'.
- The FreeBSD maintainers went through all the trouble of setting up an
easy-to-update framework, so you might as well use it.
So, the big question to you is: did you do something similar, or did you
hand-edit the sendmail.cf files?

I added the lines:
# DNSBL from http://www.ordb.org/
FEATURE(dnsbl, `relays.ordb.org', `"550 Mail from " $&{client_addr} " rejected, see http://ordb.org/"')dnl
to /etc/mail/<myhostname>. Then I typed `make; make install; make restart'
and the system worked.

What are you trying to do there?
