That occurs when the command line for Exim doesn't tell it to do
anything. In your line, you are suppying a sender address as %F and a
recipient address as %T. If one (or both) of those is actually empty,
you'll end up with a command line that says to Exim "send a message to
... " without saying who the recipient is. So you haven't given it any
recipients, nor have you given it a flag to do anything else (e.g. list
the queue).
I suspect this isn't an evil spam message, but just a bounce message
with an empty sender.
Try replacing %F with '<%F>' so that a bounce sender ends up as <>.
