Hi, I created a forum using this plugin for one of my websites. The website is an intranet. So we required everyone to subscribe to the forum. The problem is some of them receive email notifications while some of them don't. 

Am I missing something? I really need a solution for this. Any help would be great. 

Thanks, 
Matt

I'm sorry but we don't support email delivery issues. it depends on dozens of extra plugin and admin configuration issues. Here is the full list of points we recommend to check:

you should subscribe to some forum or topic, then you will get Subscription Confirmation email (check spam box too), it contains confirmation link, after clicking on that link your subscription will be activated and you'll get emails.

But before that, please set "From" email address in Forum Settings > Emails admin page. Also make sure the From email doesn't match to your profile email. "From" and "To" addresses should not be the same.
