dovecot - Jan 2018 - Duplicate mail id issue, mailbox does not exist when dovecot tries to generate a new guid so replication can take place

Hi all,

When we run the below one user constantly shows as failed (dovecot 
version is 2.2.13):

sudo doveadm replicator status "*"

mail.log shows the below for the user:

Jan? 3 16:20:57 hostname dovecot: dsync-server(user): Error: Duplicate 
mailbox GUID <guid number> for mailboxes <mailbox name.sub folder>
and
<mailbox name.sub folder> - giving a new GUID <guid number> to
<mailbox
name.subfolder>

Jan? 3 16:20:57 hostname dovecot: dsync-server(user): Error: Couldn't 
update mailbox <sub folder name> GUID: Mailbox doesn't exist: <sub 
folder name>

Looking at their mailbox the folder does exist.

Has anybody seen this before and would be aware of the way to resolve?

Kind regards

Yes with PAM config :-(.

I must setup a ldap Instance and configure the second dovecot equal to the first
dovecot!

afterward all is OK?

Hi Gunther,

Many thanks for your reply.

The main mailserver and the replication server are both LDAP connected 
already.

Kind regards
