not getting notificiation emails

It seems I am not getting email notifications for new post to threads. At least to say, this is unreliably working.

Yep, had the same impression. And it really is helpful this feature.

hmm, I got a notification for your message!

I am missing out on replies to really great threads because of this. Anyone can have a look at this?

Moderators? Owners? Please, I would be very grateful!
