Hey.

Could we see the code that is generating this error message?
It helps with the debugging process, to be able to see the code ;-)

Also, you might want to consider abandoning the old PHP mail function and try one of the PHP mailer classes, like: PHPMailer or Swift Mailer.
They are generally much easier to deal with.

Also don't forget to try the imap_mail() function.

:)
