Hi Amit, you can distinguish this two conditions as suggested from RFC 3261:
if (user not found) -> sl_send_reply("480","Temporarily Unavailable");
Yeah, the point here is:
480 Temporarily Unavailable [...] This status is also returned by a redirect or proxy server that recognizes the user identified by the Request-URI, but does not currently have a valid forwarding location for that user.
if (user not exist) -> sl_send_reply("404","NOT Found");
404 Not Found The server has definitive information that the user does not exist at the domain specified in the Request-URI. [...]
