/* NAME
/*  ext_prop 3
/* SUMMARY
/*  address extension propagation control
/* SYNOPSIS
/*  #include <ext_prop.h>
/*
/*  int ext_prop_mask(param_name, pattern)
/*  const char *param_name;
/*  const char *pattern;
/* DESCRIPTION
/*  This module controls address extension propagation.
/*
/*  ext_prop_mask() takes a comma-separated list of names and
/*  computes the corresponding mask. The following names are
/*  recognized in \fBpattern\fR, with the corresponding bit mask
/*  given in parentheses:
/* .IP "canonical (EXT_PROP_CANONICAL)"
/*  Propagate unmatched address extensions to the right-hand side
/*  of canonical table entries (not: regular expressions).
/* .IP "virtual (EXT_PROP_VIRTUAL)"
/*  Propagate unmatched address extensions to the right-hand side
/*  of virtual table entries (not: regular expressions).
/* .IP "alias (EXT_PROP_ALIAS)"
/*  Propagate unmatched address extensions to the right-hand side
/*  of alias database entries.
/* .IP "forward (EXT_PROP_FORWARD)"
/*  Propagate unmatched address extensions to the right-hand side
/*  of .forward file entries.
/* .IP "include (EXT_PROP_INCLUDE)"
/*  Propagate unmatched address extensions to the right-hand side
/*  of :include: file entries.
/* .IP "generic (EXT_PROP_GENERIC)"
/*  Propagate unmatched address extensions to the right-hand side
/*  of smtp_generic_maps entries.
/* DIAGNOSTICS
/*  Panic: inappropriate use.
