Are notification emails working properly?

Are email notifications working for anyone else? Trying to ascertain if the outgoing notification emails might not be being sent or our mail server has decided to start doing something weird with them..

The latest info that I read about it, was that it doesn't work properly and has been turned off alltogether.

FWIW, I realised some days ago that I did not receive the email messages since a few days (Sept. 18th). It seems this is fixed from 00:22 +00:00 last night since messages are now appearing in my inbox as they used to before this incident.
