I followed some instructions for installing a spam filter that didn't work out.
I can undo most of what has been done ok, but I am not sure how to undo this:
mv /var/spool/mqueue/q*/* /var/spool/mqueue
because I don't know what role the *'s play.
Would this have put all my users mail into one pile, or can I somehow undo it and recover things intact?
