In my forum, my settings are account activation by admin so I got emails every time a new user signed up because of the many bots. Since last week I haven't had any e-mails, including one to notify me of a private message. Any ideas? It was working since day one up until now. I haven't changed any of the forum settings and things like notify me of a new private message etc is still enabled.
I did recently change hosting companies a month ago but I was still receiving the emails.
I know its not a big deal since I can manually check the messages and activate/delete the new sign ups but sometimes I forget to check so the e-mails were useful.
