I have been attempting to send an email from the command line to myself, but the message does not appear in my inbox (or in spam or anywhere else). Below is the command I used, and a copy of the log. Please can anyone tell me where it is going wrong and what I can do about it.
I have exhaustively searched the web and tried many ideas, but this is the nearest I have got.

Added in response to answer by @Curtis: Perhaps I should have said that the username in the original command line was a correct user, the one I use all the time, so why would btinternet.com not recognise it?
