      5 /*	mail_error 3
      6 /* SUMMARY
      7 /*	mail error classes
      8 /* SYNOPSIS
      9 /*	#include <mail_error.h>
     10 /*
     11 /*	NAME_MASK mail_error_masks[];
     12 /* DESCRIPTION
     13 /*	This module implements error class support.
     14 /*
     15 /*	mail_error_masks[] is a null-terminated table with mail error
     16 /*	class names and their corresponding bit masks.
     17 /*
     18 /*	The following is a list of implemented names, with the
     19 /*	corresponding bit masks indicated in parentheses:
     20 /* .IP "bounce (MAIL_ERROR_BOUNCE)"
     21 /*	A message could not be delivered because it was too large,
     22 /*	because was sent via too many hops, because the recipient
     23 /*	does not exist, and so on.
     24 /* .IP "2bounce (MAIL_ERROR_2BOUNCE)"
     25 /*	A bounce message could not be delivered.
     26 /* .IP "data (MAIL_ERROR_DATA)"
     27 /*	A message could not be delivered because a critical data
     28 /*	file was unavailable.
     29 /* .IP "policy (MAIL_ERROR_POLICY)"
     30 /*	Policy violation. This depends on what restrictions have
     31 /*	been configured locally.
     32 /* .IP "protocol (MAIL_ERROR_PROTOCOL)"
     33 /*	Protocol violation. Something did not follow the appropriate
     34 /*	standard, or something requested an unimplemented service.
     35 /* .IP "resource (MAIL_ERROR_RESOURCE)"
     36 /*	A message could not be delivered due to lack of system
     37 /*	resources, for example, lack of file system space.
     38 /* .IP "software (MAIL_ERROR_SOFTWARE)"
     39 /*	Software bug. The author of this program made a mistake.
     40 /*	Fixing this requires change to the software.
