Hi,

We're synching mailboxes, changing format from maildir to mdbox, using doveadm backup/doveadm sync.

When still running 2.2.36, 'doveadm backup' also synched the sieve scripts, without issues.

After the upgrade to 2.3.5.1, the sieve sync stopped working. We're using the pre-built 2.3 packages from https://repo.dovecot.org/ce-2.3-latest/debian/stretch

In fact, when I now remove the dovecot-2.3 packages, and use my own old 2.2.36 packages, using the exact same config, the sieve scripts are being copied again.

In 2.2.36, when I migrate a mailbox, I do see Pigeonhole being initialized. Eg:

Afterwards, the sieve scripts have been transferred, even including last-modified time of any scripts.

However, with 2.3.5.1, it seems doveadm-sieve is never called from dsync. Output includes:

In the above output from 2.3.5.1, all lines starting with "Debug: doveadm-sieve: Iterating Sieve mailbox attributes" are absent. I have no idea why.

We can "work around" it by explicitly doing an rsync of the sieve storage after the migration, but that's a bit of a hack.

Attached is a doveconf -n output for 2.3.5.1.
