cannot send mail using php mail function

Question

Im trying to use PHP mail on my local computer, but its just not working. I am using the standard script from the php website:

PHP error I'm getting

SMTP server response: 550 Error sending message: Error: FROM address is invalid

actual PHP

$to      = 'nobody@example.com';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: webmaster@example.com' . "\r\n" .
    'Reply-To: webmaster@example.com' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);

i downloaded a local mail server, argosoft. it says the service URL is http://services.argosoft.com/RelayService/Service.asmx . I assume this is what i put in php.ini.

php ini.

 For Win32 only.
 SMTP = services.argosoft.com/RelayService/Service.asmx
 smtp_port = 25

Answer 1

I have had this error before, and I believe all you have to do is change the email webmaster@example.com to a real email. Make sure you send it to a real email as well.

Answer 2

Replace @example.com with real email addresses.

and in PHP.ini set

SMTP = localhost

Answer 3

Apparently, a number of mail systems have trouble with the carriage return \r. You might want to modify your $header to use only the new line character \n. See if that works.

Also, you might want to try using the full From header:

From: Some Name Here <real_email@notAnExample.com>
