hi
see sending a text mail is very simple using the mail() function in PHP.
By the way you can add information other than subject,body,from,
like
content typ
Mailer Verison etc...
A Simple will be as follows
<?
$address="php@php.com";
$subject="check this!";
$body="bla ..bla...";
$from="s.r.k@onebox.com";
mail($address,$subject,$body,$from);
$smile="🙂";
echo("I have sent my mail successfully".$smile);
?>
//If this doesnt work let me know ...
