Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

   We have two mailservers, mail replication works as expected, sieve script
replication does not, tasks affected:

   creating/activating/de-activating/deletion/amendment of a script of an
active or non-active script.

   An error is only reported in the logs on de-activating a script as below:

   Oct  9 15:18:14 hostname dovecot: dsync-local(user): Debug: doveadm-sieve:
Iterating Sieve mailbox attribute:

script: Opened script `0910-newactive' from

   Jessie packages only creation and deletion of scripts is sync'd - 2.2.13
   Stretch packages, creating/activating/de-activating/deletion is sync'd,
amendment of an active/non-active script is not sync'd - 2.2.27

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

   Updated Dovecot packages (Buster 10.0) to the latest provided on
repo.dovecot.org:

   ii  dovecot-core                  2:2.3.8-4~buster            amd64
secure POP3/IMAP server - core files
   ii  dovecot-imapd                 2:2.3.8-4~buster            amd64

   ii  dovecot-ldap                  2:2.3.8-4~buster            amd64

secure POP3/IMAP server - Sieve filters support

   * What was the outcome of this action?

   Sieve replication worked as expected (creating/activating/de-
activating/deletion/amendment of a script of an active or non-active script)

   * What outcome did you expect instead?

Hi,

As this is now resolved in the stated package would it be possible to
backport this, so this functionality is available for stable?

Kind regards

Could this be the same problem as described in this bug report:

There is also a patch linked that you could try.
