smfi_setreply

smfi_setreply(3N)														 smfi_setreply(3N)

NAME

       smfi_setreply() - sets the default SMTP error reply code

SYNOPSIS

PARAMETERS

       ctx	 Specifies the opaque context structure.

       rcode	 Specifies the 3-digit (RFC 821/2821) SMTP reply code as a null-terminated string.  rcode cannot be set to NULL value.	rcode must
		 be a valid or reply code.

       xcode	 Specifies the extended (RFC 1893/2034) reply code.  An xcode must conform to RFC 1893/2034.  If xcode is set to NULL, an extended
		 code is not used.

       message	 Specifies the text part of the SMTP reply.  If message is set to NULL, an empty message is used.

DESCRIPTION

       The  routine  directly sets the SMTP error reply code for a connection.	Only and replies are accepted.	uses this code on subsequent error
       replies from the Milter function.

       can be called from any function except the function.

   Notes
       o  Values passed to are not checked for standards compliance.

       o  The message parameter must contain only printable characters; other characters may lead to undefined behavior.  For example,	CR  or	LF
	  causes  the call to fail, a single (percentage) character can cause the text to be ignored.  If a (percentage) character must be used in
	  a string, it must be used as

       o  For more information on reply codes and their meanings, see RFC 821, 2821, 1893, or 2034.

       o  If the reply code (rcode) given is a code but is used for the message, the normal reply is not used.

	  If the reply code (rcode) given is a code but is used for the message, the custom reply is not used.

	  In neither of these two cases, an error is returned to the Milter and silently ignores the reply code.

       o  If the Milter returns and sets the reply code to the SMTP server terminates the SMTP session with a error code.

RETURN VALUE

       fails and returns if the rcode or xcode argument is invalid or a memory allocation failure occurs; otherwise; returns

       The routine was developed by the Sendmail Inc.
