That is a good tip as well. I had followed this bit of experience from someone else: https://marc.info/?l=dovecot&m=164438199727640 <https://marc.info/?l=dovecot&m=164438199727640>, haven't seen any err message since. But that might be because they are in sync now and both sides are aware. Can I trigger full replication again so I can test? Gerben
