I just installed YAF on DNN 5 and so far I'm thoroughly impressed. Everything is working flawlessly with the exception of email notifications of new posts. They simply aren't happening (or more precisely I'm not receiving any in my inbox). Relevant info:
1.) YAF Version: 188.8.131.52 (Date: 3/3/2011)
2.) When I test the SMTP through the install process, there are no problems, the email is received fine.
3.) There aren't any error messages in either the DNN log or the YAF log.
4.) My account that I'm using for testing has it's email notification preferences set to Notification for topics you've posted to, watched or marked as favorite and the topic I'm testing with is on the watch list.
5.) The MailSendTask under YAF>Maintenenace>Task Manager is running.
6.) SMTP is working fine on my site as I have numerous email jobs that occur daily without problems.
Any guidance would be greatly appreciated. It's the last install/setup issue that I need to resolve before I can go live with the new forum.
P.S.On a related note, just an FYI, when I registered for the YAF support forum, it sent me 6 identical emails about registration verification.
