Mail acting finicky

[corman420]

My send mail doesn't seem to be sending to external addresses.

This script, will not send to my email address. But when I use an internal email address (a domain that is on the server), it works fine.

My vbulletin script works fine. What's that all about. I can signup on vbulletin, and get the mail to an external address. As far as I know, vbulletin uses php to send mail as well. So Im stunned. I have no idea what's going on.

$email = " [email protected]";
$subject = "Test Subject";
$message = "This is a test";
mail($email,$subject,$message);

I did recently have another server in the same data centre. All the account were on both servers. Each server has different DNS settings. On the old server I had the mail pointing to the new servers IP address. I did find a few mails going to the old server. But some are just lost entirely.

This still doesn't explain why I can't use the normail mail() function to send mail to an external address.

Any thoughts from anyone?

Here's something to ponder, maybe someone has an answer. Safemode is OFF on my domains. But when I use -f in my mail() function, it works. Odd....
