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:
userimap-dev1:~ # doveadm -D backup -u xtra30 "doveadm -D dsync-server -u xtra30+mdbox=.8d1&4&03&xtra30"
(note: that strange destination user signals to the auth proxy that we want the new mdbox storage instead of the default for this user)

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.
