Heathrow say there are postboxes before and after security at each terminal but I've never found them personally (ok, I've never looked very hard either). If you want a post office, you're going to T3 unfortunately (the only one at any Heathrow terminal).
I don't need them very often but when I do, I'm usually in a position of absolutely having to post something before I fly, which I suspect is fairly common among business travellers. It's not ideal but probably realistically in line with the demand for such...
