Are you passing the email field to the script?

[code]
<input type="text" name="email" size="20">
[/code]


[code]
$to = "$email";
$subject = "Hi!";
$body = "Hi,\n\nHow are you?";
if (mail($to, $subject, $body)) {
  echo("<p>Message successfully sent!</p>");
} else {
  echo("<p>Message delivery failed...</p>");
}
[/code]

I assume that by:[quote]phpsendmail[/quote]You really mean: [code]mail();[/code]
Its really easy actually, mail() accepts four arguments, a 'to' string, a 'subject' string, a 'message' string, and optional additional headers, here's an example:
[code]$to = "[email protected]";
$subject = "My First PHP-Sent EMAIL!";
$message = "I am invincible!";
mail( $to, $subject, $message );[/code]
That's it! There are a few caveats though. The 'subject' string cannot contain any newline (\n) characters. The 'message' string's lines need to be less than 70 characters. And obviously, the 'to' string needs to be a valid email address. mail() doesn't return many (any that I've seen) error messages, so that can make troubleshooting a pain. The server on which you are running the script needs to have the sendmail daemon running, or else the mail wont get through (Assuming you're running it on a *nix box, no idea what needs to be there for Windows). Start small, make a little test script to email yourself, make sure it works, then expand it to "invite your friends".

You run either one of these scripts, no, you shouldn't
