I have the same issue with thunderbird, in a master-master setup. If I 
use sieve, the message does not get duplicated. Hence, it might be an 
issue with thunderbird.

I'm not really sure, the root cause of the issue. I would be interested 
in knowing the solution as well.

FYI: I'm on dovecot 2.2.6 and I'm using DSYNC based replication (over ssh)
