How do I send email using php via wamp? - wamp

Question

I want to use wamp as my development server and I'm trying to send email via my email => gmail, hotmail, yahoo. I'm trying to implement a simple email php application.
Is it possible to do it in wamp?
Is it possible to do it without changing php.ini and instead use ini_set();
I have tried changing my php.ini
using my yahoo mail
SMTP = smtp.mail.yahoo.com
; http://php.net/smtp-port
smtp_port = 587
auth_user = me#yahoo.com
auth_pass = password
and got this error message "Warning: mail() [function.mail]: SMTP server response: 530 authentication required - for help go to http://help.yahoo.com/help/us/mail/pop/pop-11.html in C:\wamp\www\9dot_disc_alt\abc.php on line 12"
using gmail
SMTP = smtp.gmail.com
; http://php.net/smtp-port
smtp_port = 587
auth_user = me#gmail.com
auth_pass = password
SMTP server response: 530 5.7.0 Must issue a STARTTLS command first. pc6sm6631754pbc.47 in C:\wamp\www\9dot_disc_alt\abc.php on line 12
Here's my current code:
$to = "me#yahoo.com";
$subject = "Test mail";
$message = "Hello! This is a simple email message.";
$from = "me#my.com";
$headers = "From:" . $from;
mail($to,$subject,$message,$headers);
echo "Mail Sent.";
Sir/Ma'am your answers would be of great help and be very much appreciated. Thank you++

Answer 1

When you use wamp, your SMTP must be your FAI, for example if you have free :
=>SMTP = smtp.free.fr (or .com)
EDIT : You can try this : http://glob.com.au/sendmail/, i's a simple windows console application that emulates sendmail's for wamp for example ;)
