Issue: Not receiving e-mail notification of new PM's

I've been receiving an e-mail each time I got a PM, whether it be a bank transfer notification, a card received, or a PM from another member... but lately, I noticed that I stopped getting them. This may have to do with the fact that I turned off pop-up notifications of PM's recently... but these are two separate settings, so I don't think they should affect each other. It may just be a coincidence that I'm not getting the e-mails anymore...

I have not changed my e-mail address ever.

Anyone else who turned off pop-up notification of PM's also stop receiving e-mail notifications of PM's?
