I'm waiting on receiving an email from someone, they said they have sent it ... They've checked their sent items and it sent, so they've re sent it. I still have no received it. I tried sending myself an email, (I received my standard saved message, but not the actual sent email) ... I've sent from another account, I received that email plus I've also received a few other emails from other people.

I have checked my safe and blocked senders etc, but there is no one in there. I have checked and cleared my junk and trash, why am I all of a sudden not receiving some emails? It's rather frustrating, I've never had this problem before! Please help!
