/* NAME
/*  mail_dict 3
/* SUMMARY
/*  register application-specific dictionaries
/* SYNOPSIS
/*  #include <mail_dict.h>
/*
/*  void    mail_dict_init()
/* DESCRIPTION
/*  This module registers dictionary types that depend on higher-level
/*  Postfix-specific interfaces and protocols.
/*
/*  This also initializes the support for run-time loading of
/*  lookup tables, if applicable.
/*
/*  The latter requires basic parameter initialization
/*  by either mail_conf_read() or mail_params_init().
/* LICENSE
/* .ad
