/* NAME
/* trace 3
/* SUMMARY
/* user requested delivery tracing
/* SYNOPSIS
/* #include <trace.h>
/*
/* int trace_append(flags, id, stats, rcpt, relay, dsn)
/* int flags;
/* const char *id;
/* MSG_STATS *stats;
/* RECIPIENT *rcpt;
/* const char *relay;
/* DSN *dsn;
/*
/* int trace_flush(flags, queue, id, encoding, sender,
/* dsn_envid, dsn_ret)
/* int flags;
/* const char *queue;
/* const char *id;
/* const char *encoding;
/* const char *sender;
/* const char *dsn_envid;
/* int dsn_ret;
/* DESCRIPTION
/* trace_append() updates the message delivery record that is
/* mailed back to the originator. In case of a trace-only
/* message, the recipient status is also written to the
/* mailer logfile.
/*
/* trace_flush() returns the specified message to the specified
/* sender, including the message delivery record log that was built
/* with vtrace_append().
/*
/* Arguments:
/* .IP flags
/* The bitwise OR of zero or more of the following (specify
/* BOUNCE_FLAG_NONE to request no special processing):
/* .RS
/* .IP BOUNCE_FLAG_CLEAN
/* Delete the logfile in case of an error (as in: pretend
/* that we never even tried to deliver this message).
/* .RE
/* .IP queue
/* The message queue name of the original message file.
/* .IP id
/* The message queue id.
/* .IP encoding
/* The body content encoding: MAIL_ATTR_ENC_{7BIT,8BIT,NONE}.
/* .IP sender
/* The sender envelope address.
/* .IP dsn_envid
/* Optional DSN envelope ID.
/* .IP dsn_ret
/* Optional DSN return full/headers option.
/* .IP stats
/* Time stamps from different message delivery stages
/* and session reuse count.
/* .IP rcpt
/* Recipient information. See recipient_list(3).
/* .IP relay
/* The host we sent the mail to.
/* .IP dsn
/* Delivery status information. See dsn(3).
/* 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.
