SMTP :: boolean recv ( resource connection, integer first_code [, integer second_code ] )
Return TRUE if the code has been successfully received, FALSE if not. Example:

// connect to 'smtp.hostname.tld' port '25'
$c = fsockopen('smtp.hostname.tld', 25, $errno, $errstr) or die($errstr);

// expect response code '220'
$r = SMTP::Recv($c, 220);

// print result
if ($r) echo 'Successfully received !';
else print_r($_RESULT); // <- for debugging
