Look at your logs on darwin.ctyme.com. It submitted the message to the
list server twice:

Received: from smtp8.junkemailfilter.com ([69.50.231.8]:33800
helo=darwin.ctyme.com) by sesame.csx.cam.ac.uk with esmtp (Exim 4.54) id

Interesting that you mention bsmtp in your post - if that fails when the
sending end thinks the message is not complete, but the receiving end
thinks it is, you can get duplication. You shouldn't, but you can. You
should always autoflush buffers if you're wrapping the pipe in a script.
