Both of these appear to have been renamed: WITHOUT_SENDMAIL and
WITHOUT_IPFILTER.  You can poke around at things in
src/tools/build/options/ and see what's what.

However, I'm not sure how these play a role with world right now.  I'm
not entirely familiar with how (if at all) src/tools/build/options/
actually controls buildworld/isntallworld features.  Someone else will
have to comment on that.

Regarding concerns over mailer selection:

Which mailer gets used for commands like sendmail(8), newaliases(1),
mailq(8) and others is enitrely based on /etc/mail/mailer.conf.  The
actual binaries on FreeBSD of /usr/sbin/sendmail, /usr/bin/newaliases,
etc. are all wrappers that read /etc/mail/mailer.conf to determine what
program to actually execute.

So it's "generally safe" to have both sendmail (the MTA/MDA) from the
base system installed at the same time as postfix.
