dovecot - Sep 2018 - Failed to get attribute vendor/vendor.dovecot/pvt/server/sieve/default

Any ideas what this cryptic message means ? Despite what the message says, there
is no "more information" to be found in the logs on either server !

doveadm-backup returns exit code 75, something which also appears to be
documented nowhere !

Hi!

Can you check server logs for any further logs? Do you have
mail_attribute_dict setting?
