Update to 0.7.9.
  Changes in release 0.7.9
    - Added LogTag option to asmtpd.conf.
    - Fix err_accum in default unknown script, as Tim Kientzle reports the
      old script did not work on FreeBSD.
    - Added MSGID environment variable.
    - Added IdentTimeout option to asmtpd.conf.
    - Addes support for newer DB versions.
  Changes in release 0.7.8
    - Fixed bug where first group of avenger user could disappear on systems
      with HAVE_EGID_IN_GROUPLIST defined (i.e., FreeBSD).
    - Added --map option to aliascheck.  Make sample unknown file check
      recipient in virtusertable.db if one exists.
    - SMTPCB can now take on three values, 0, 1, and 2.  2 is equivalent to
      the old behavior (do SMTP callbacks and reject mail when the callback
      fails).  0 disabled the callbacks entirely.  1 performs the callbacks
      but does not reject mail that fails.
    - Added an InsecureSASL option to asmtpd.conf.
    - Make SASL accept plaintext authentication after STARTTLS, even if
      there was an EHLO call before the STARTTLS.
    - Fixed a bug in avenger.local when no .avenger/local file exists.
