<TABLE border="1" cellspacing=0>
<TR bgcolor="#dddddd"><TH>Argument</TH><TH>Description</TH></TR>
<TR valign="top"><TD>ctx</TD>
<TD>Opaque context structure.
</TD></TR>
<TR valign="top"><TD>rcode</TD>
<TD>The three-digit (RFC 821/2821) SMTP reply code, as a
null-terminated string. rcode cannot be NULL, and must be a valid
4XX or 5XX reply code.
</TD></TR>
<TR valign="top"><TD>xcode</TD>
<TD>The extended (RFC 1893/2034) reply code. If xcode is NULL, no
extended code is used. Otherwise, xcode must conform to RFC 1893/2034.
</TD></TR>
<TR valign="top"><TD>message</TD>
<TD>The text part of the SMTP reply. If message is NULL, an empty message is used.
</TD></TR>
</TABLE>
</TD></TR>
<!----------- Return values ---------->
<TR>
<TH valign="top" align=left>RETURN VALUES</TH>
<TD>smfi_setreply will fail and return MI_FAILURE if:
<UL>
<LI>The rcode or xcode argument is invalid.
<LI>A memory-allocation failure occurs.
</UL>
Otherwise, it return MI_SUCCESS.
</TD>
</TR>
<!----------- Notes ---------->
<TR align="left" valign=top>
<TH>NOTES</TH>
<TD>
<UL>
<LI>Values passed to smfi_setreply are not checked for standards compliance.
<LI>The message parameter should contain only printable characters,
other characters may lead to undefined behavior.
For example, CR or LF will cause the call to fail,
single '%' characters will cause the text to be ignored
(if there really should be a '%' in the string,
use '%%' just like for <TT>printf(3)</TT>).
<LI>For details about reply codes and their meanings, please see RFC's
<A href="http://www.rfc-editor.org/rfc/rfc821.txt">821</A>/
<A href="http://www.rfc-editor.org/rfc/rfc2821.txt">2821</A>
and
<A href="http://www.rfc-editor.org/rfc/rfc1893.txt">1893</A>/
<A href="http://www.rfc-editor.org/rfc/rfc2034.txt">2034</A>.
<LI>If the reply code (rcode) given is a '4XX' code but SMFI_REJECT is used
for the message, the custom reply is not used.
<LI>Similarly, if the reply code (rcode) given is a '5XX' code but
SMFI_TEMPFAIL is used for the message, the custom reply is not used.
<BR>
Note: in neither of the last two cases an error is returned to the milter,
libmilter silently ignores the reply code.
<LI>If the milter returns SMFI_TEMPFAIL and sets the reply code to '421',
then the SMTP server will terminate the SMTP session with a 421 error code.
