dsync replication issue

[Cédric ML]

Hello,

I'm facing a problem with dsync : replication between my two dovecot 
2.2.10 servers (10.10.10.10 = serverA and 10.10.10.11 = serverB) is not 
done when a mail is received on any of the two servers.
Sync is correctly working when running "doveadm [-D] sync -A 
tcp:10.10.10.10:12345" from serverB or "doveadm [-D] sync -A 
tcp:10.10.10.11:12345" from serverA
Sieve vacation message replication is functional too, and triggered when 
a change is done on any of the two servers.

I guess it's a notify problem, but I did not find how to debug it... 
I've enabled dovecot debug, but I don't see anything related to notify 
in logfile.
Here's my doveconf -n (it's the same on the two servers, except IP 
address changes)

Hope somebody will be able to help me.

Regards,
Cédric
