I have installed and setup Bugzilla3 for my domain. Everything is working properly except for the email functionality. The server uses Postfix, and that works for my PHP application, and command line. In Bugzilla, I have tried setting the mail_delivery_method to 'test', and nothing shows up in data/mailer.testfile, it is completely blank... I have no idea where to go from here, any ideas on what to try next?
