mail() problem

[albert22]

I can't send a basic mail.
I used the next source:

<?php
ini_set ( "smtp_port", 25 );
ini_set ( "smtp", "smtp.frandt.com" );
ini_set ( "sendmail_from", "[e-mail]" );
echo "it must work" ;
mail("[e-mail]", "My Subject", "Test");
?>

I uploaded my file to the server. The browser didn't send me any error.
What should I do, what's wrong?

why are you using the ini_set. Shouldn't that already be set in the php.ini file.

[albert22]

The master values are:
smtp=localhost
smtp_port=25
sendmail_from=postmaster@localhost

After the execution of the ini_set the local value are:
smtp=localhost
smtp_port=25
senmail_from=[e-mail]

I don't know why I can't change smtp.
If you know a method to change these values (smtp, sendmail_from) in another way please tell me.

This is how I did it in the past.

<?php
mail("[e-mail]", "the subject", $message,
""From: YOUR_EMAIL_HERE"); ");
?>
