yeah this just started for me too, also on BT. I suspected it was them when a friend of mine in the states had gets break and it turned out to be her ISP too. I am able to send fine, and the get trouble is intermittent as I managed to recieve a .jpg from someone fine, but a .zip and a .mp3 both said no.
I don't use the default ports either I wonder how they do it.
Time for mass calls to BT I think.
