dovecot duplicate emails

Tue Sep 10 15:49:45 EEST 2019

Hello. I have problems with duplicate emails when using replication and 
configured message filters on the client.
Looks like when letter comes, it processed by replication and 
immediately after this processed by filter on client and moved to 
another folder.
When it arrives to slave server into INBOX, it replicated back to master 
into INBOX and only after that - slave receives MOVE command.
The only thing I see in the log is that the letter comes 2 times with 
same msgid:
