This log looks like you timed out the bell.ca sending server after 2 minutes. You closd the connection - and so how do you expect them to send a QUIT? Additionally - you aborted the stream mid-DATA command - you have 1) no guarantee thatyou've received the whole message*** and 2) bell.ca has no confirmation that you've received the message - so their server will retry. *** If you know you received the whole message (i.e. bell.ca sent the CRLF.CRLF and you're now 'doing your thing' before deciding to accept or reject the message) then you've set your 2 minute timeout way too low and you need to work out how to complete your processing within your own timeout.
