The login credentials are all correct, as the test email will send to the desired address (sending from firstname.lastname@example.org to my personal email), but the header information is incorrect. The From Name field clearly says Support Team, but the email says it was received from Feedback Form. I used to have PHP PEAR installed with a form that would send with those credentials, but I've since uninstalled PEAR. Is there a configuration file that I missed? Why is it sending with incorrect headers?
Running on Ubuntu 12.10 x86.
Edit - I tried another email address, it too chose to send with the name Feedback Form.
Edit 2 - Ran
apt-get purge php-pear; problem is persisting.
