Hello,

exim4 used to be linked against libwrap in the beginning, we dropped
it for these reasons:

- exim v3 was not linked against libwrap and switching from v3 to v4
  would have broken installations with strict libwrap setup. (ALL: ALL
  in host.deny.)

- Exim has built-in support for this (acl_smtp_connect).

- On non-internet systems in the default Debian configuration exim4
  does not even listen on public interfaces.
