php - Checking Email exists via Proxy -

i've got code checks mailserver existence of email address.

i use open connection directly.

fsock = @fsockopen($mxhost, 25, $errno, $error, $this->con_timeout) 

however, unable figure out how process via socks proxy username , password.

can me out?

lets more concise:

$proxy = "1.2.3.4"; // proxy  $port = 8080; // proxy port  $fp = fsockopen($proxy,$port); // connect proxy fputs($fp, "connect $mailserver:25 ......"); 

i'm not sure fputs syntax should be.

thanks
