hola creo que aparte de un aporte quisiera saber con ustedes colegas si esto podria resultar...encontre un codigo para saber si el e-mail existe...no de ke si existe en la bd si no ke si existe en el hotmail o cualquiera...osea si el mail esta registrado o no
Código PHP:
// Step 4 -- Connect to mail server and check e-mail address (OPTIONAL)
// Finally, once you have the best guess at a mail server, it's time to open a connection and talk to the server. As I stated earlier, this step is optional. After every command you send, you'll need to read a kilobyte (1024 bytes) of data from the server. It should be more than enough to receive the complete response from the server for that command.
// Note that you'll store the output from the server in three separate variables: $To, $From and $Out. This is done so you can check the responses after you close the connection, to see if you actually have a real e-mail address or not.
// If the script cannot connect at all, or the e-mail address wasn't valid, set the $result array to the proper values:
$Connect = fsockopen ( $ConnectAddress, 25 );
if ($Connect) {
if (ereg("^220", $Out = fgets($Connect, 1024))) {
fputs ($Connect, "HELO $HTTP_HOST\r\n");
$Out = fgets ( $Connect, 1024 );
fputs ($Connect, "MAIL FROM: <{$Email}>\r\n");
$From = fgets ( $Connect, 1024 );
fputs ($Connect, "RCPT TO: <{$Email}>\r\n");
$To = fgets ($Connect, 1024);
fputs ($Connect, "QUIT\r\n");
fclose($Connect);
if (!ereg ("^250", $From) ||
!ereg ( "^250", $To )) {
$result[0]=false;
$result[1]="Server rejected address";
return $result;
}
} else {
$result[0] = false;
$result[1] = "No response from server";
return $result;
}
} else {
$result[0]=false;
$result[1]="Can not connect E-Mail server.";
return $result;
}
// Step 5 -- Return the results
// Finally, our last and easiest step is to return the results and finish:
$result[0]=true;
$result[1]="$Email appears to be valid.";
return $result;
} // end of function
}
