I'd try this (in shell):

doveadm search -u user at domain.net mailbox inbox | wc -l

Doveadm will print mailbox-guid and uid pair for every message in inbox, 
one per line, pipe it into "wc -l", which will count the lines and 
output a number - that's the count of messages in INBOX.

Then try doveadm deduplicate and after that the search command above 
again. If the count changed, deduplicate is working - you may only need 
to run it multiple times.

If the count doesn't change, dovecot is unable to recognize duplicates 
in your mailbox and you need to find another solution. Maybe check out 
the "-m" option in man doveadm-deduplicate
