I'm having trouble getting notification emails to send. I've been tinkering with function pfund_send_donate_email in user.php and function pfund_handle_publish in admin.php. I can get it to fire off a test wp_mail message (without any of your variables) before the first if statement, but not after that - but at least I know the system is making its way to the right functions.
I'm not sure if this is part of it, but those if statements reference filters called pfund_mail_on_publish and pfund_mail_on_donate which I don't see listed in hooks.php.
I was originally worried something was going on with wp_mail but that doesn't seem to be the case. I'm stuck. Help!
I was still running 3.4.2 but upgraded to 3.5.1 before I submitted this question just in case. Same issue on both. All other functionality seems to be working swimmingly though.
