Question Not receiving email notifications

I'm not sure if this is a kunena issue, a server issue, or something else. I'm going to start here and narrow it down.

For the last few days I haven't been receiving all of my email notifications, either when a new post is created in a subscribed board, or a reply to a subscribed thread. Sometimes I do receive the notification in Tapatalk, but not even always in Tapatalk. It seems that new posts are not registering properly.

As far as I know, everything is up to date.

Here's my configuration report.
