Looks like it was my bad. The e-mails went into my junk folder for some reason. Windows Mail's spam filter seems to be extremely strict... that's not the first legitimate e-mail that I've found in there.
Back on topic: Is there any chance that this will actually get fixed? I guess it's not that big of a deal for me because I played with the cache disabled last night and it seemed to load and update stats very quickly, but then again my lolmaha databases are quite small right now.
