   6 /* SUMMARY
   7 /*      pre-defined mail addresses
   8 /* SYNOPSIS

  16 /* DESCRIPTION
  17 /*      This module predefines the following addresses:
  18 /* .IP MAIL_ADDR_POSTMASTER
  19 /*      The postmaster handle. Typically used for sending mail to.
  20 /* .IP MAIL_ADDR_MAIL_DAEMON
  21 /*      The mailer-daemon handle. Typically used to bring bad news.
  22 /* .IP MAIL_ADDR_EMPTY
  23 /*      The empty mail address. This refers to the postmaster on the
  24 /*      local machine.
  25 /* .PP
  26 /*      mail_addr_double_bounce() produces the fully-qualified version
  27 /*      of the local double bounce address.
  28 /*
  29 /*      mail_addr_postmaster() produces the fully-qualified version
  30 /*      of the local postmaster address.
  31 /*
  32 /*      mail_addr_mail_daemon() produces the fully-qualified version
  33 /*      of the local mailer-daemon address.
  34 /* CONFIGURATION PARAMETERS
  35 /*      double_bounce_sender, the double bounce pseudo account.
  36 /*      myhostname, the local machine hostname.
  37 /* BUGS
  38 /*      Addresses are constructed by string concatenation, instead of
  39 /*      passing them to the rewriting service.
