A dingo stole my baby!

Wait, wrong forum. Today I had an email, so whent in to read it and there are only 3 emails in it. Last time I looked they were all there and I haven't fiddled around during that time. There are also 2 inbox's for some reason.

Does anyone have any idea about this? I searched but couldn't find anything about this. I haven't restarted yet to find out if the problem just goes away on a restart.

I shall go restart now and see what happens.

Thanks for any help.

edit: I should mention that all my sent mails are still there.
