  Hmm, odd. The above log only shows one delivery. I would expect a 
duplicate entry there when Dovecot is causing this. You can enable 
mail_debug to see whether that shows more. Also, the user log 
(~/.dovecot.sieve.log) could contain other info. But, I don't expect 
much more from that.

Are you perhaps doing something interesting at MTA level?
