I'm sending many mails in different languages, but the header of the mail appears all the time in English (eg. Date: Wed, 25 Jul 2007 03:20:02 +1200 [07/25/2007 03:20:02 AM FJT] ), and not in the selected language. I'm using PHP 5.2.0 and PHPMailer Class for sending mails. How can I change the header to the selected language? ( so for german users showing the date in german format and so on).
