Exim version 4.69
-----------------

TK/01 Add preliminary DKIM support. Currently requires a forked version of
      ALT-N's libdkim that I have put here:
      http://duncanthrax.net/exim-experimental/

      Note to Michael Haardt: I had to rename some vars in sieve.c. They
      were called 'true' and it seems that C99 defines that as a reserved
      keyword to be used with 'bool' variable types. That means you could
      not include C99-style headers which use bools without triggering
      build errors in sieve.c.

NM/01 Bugzilla 592: --help option is handled incorrectly if exim is invoked
      as mailq or other aliases.  Changed the --help handling significantly
      to do whats expected.  exim_usage() emits usage/help information.

SC/01 Added the -bylocaldomain option to eximstats.

NM/02 Bugzilla 619: Defended against bad data coming back from gethostbyaddr

NM/03 Bugzilla 613: Documentation fix for acl_not_smtp

NM/04 Bugzilla 628: PCRE update to 7.4 (work done by John Hall)
