/* NAME
/* verify 3
/* SUMMARY
/* update verify database
/* SYNOPSIS
/* #include <verify.h>
/*
/* int verify_append(queue_id, stats, recipient, relay, dsn,
/* verify_status)
/* const char *queue_id;
/* MSG_STATS *stats;
/* RECIPIENT *recipient;
/* const char *relay;
/* DSN *dsn;
/* int verify_status;
/* DESCRIPTION
/* This module implements an impedance adaptor between the
/* verify_clnt interface and the interface expected by the
/* bounce/defer/sent modules.
/*
/* verify_append() updates the address verification database
/* and logs the action to the mailer logfile.
/*
/* Arguments:
/* .IP queue_id
/* The message queue id.
/* .IP stats
/* Time stamps from different message delivery stages
/* and session reuse count.
/* .IP recipient
/* Recipient information. See recipient_list(3).
/* .IP relay
/* Name of the host we're talking to.
/* .IP dsn
/* Delivery status information. See dsn(3).
/* The action is one of "deliverable" or "undeliverable".
/* .IP verify_status
/* One of the following recipient verification status codes:
/* .RS
/* .IP DEL_REQ_RCPT_STAT_OK
/* Successful delivery.
/* .IP DEL_REQ_RCPT_STAT_DEFER
/* Temporary delivery error.
/* .IP DEL_REQ_RCPT_STAT_BOUNCE
/* Hard delivery error.
/* .RE
/* DIAGNOSTICS
/* A non-zero result means the operation failed.
/*
/* Fatal: out of memory.
/* BUGS
/* Should be replaced by routines with an attribute-value based
/* interface instead of an interface that uses a rigid argument list.
/* LICENSE
/* .ad
/* .fi
/* The Secure Mailer license must be distributed with this software.
