Changelog:
==========
- The msmtpq script was updated.
- Added a new configuration command 'eval' to replace the current configuration
  file line with the output of a command (similar to passwordeval, but more
  general).
- Added a new configuration command 'set_msgid_header' with the default setting
  'auto'. This adds a Message-ID header to the mail if none is present.
- msmtpd now adds a Received header
