I'm having the same problem. It's due to the mail server set to AUTH permissions for mail relay via SMTP. The only way I know of to make it work is to open up your mail server to act as a full mail relay, letting spammers do what they want... Not a happy solution.
Now I ask this question again. How do I send a valid AUTH header in a PHP mail() request? -- PHP Windows Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
