Hello,
we are using dovecot 2.2.13 on debian jessie from default repositories in multiple two node replication cluster. For another cluster I was trying to set this up on debian stretch with current dovecot 2.2.27.
It seemed that notifiy was not working at all. Running replicate manually did work though.
I found several mailing list questions regarding this issue. It looks like there is some locking issue with maildir storage engine or notifying the replicator might not work. Tried to setup sdbox without any improvements.
In version 2.2.31 there is a change in the changelog:
- imap: NOTIFY command has been almost completely broken since the beginning. I guess nobody has been trying to use it.
Question 1: Is this change regarding the notify process that notifies the replicator?
Question 2: When will this version be available on dovecot stretch-auto repository? I installed sid version to test.
Question 3: What else can I do to make replication work?
Thanks,
Vitali
