cvsup updates the FreeBSD source tree to whatever the developers have
committed. A patch for the issue (not an update to 8.13.6) was applied
to most branches.

Yes, you are now running sendmail 8.13.6. No, this is probably not the
best way to patch a production server :) For a small version bump like
the sendmail one, you didn't break anything, but in general, replacing
part of the base system wholesale could cause problems due to
dependencies of other parts of the sytem on a particular version, or
different compile-time settings between FreeBSD and the source
distribution. Just running cvsup, verifying that you now have the
version numbers listed in the security advisory, and rebuilding what
the advisory tells you to, would have sufficed.
