Hi Timo, here's the config, the sieve section is at the bottom. Also,
note that due to upgrading Dovecot over the years, we have an odd "home"
folder situtation, where it's actually IN the main maildir folder,
rather than being its parent.

Greetings,
On 2.3 I was able to run the following command, but now on 2.4 I'm getting the
following error:
doveadm backup -u u...@domain.tld maildir:/mnt/backups/daily/domain.tld/user
dsync(u...@domain.tld): Error: brain M: Exporting mailbox INBOX failed: Mailbox
attribute iteration failed: Mailbox attributes not enabled
This is actually wrong error message, which shouldn't have been logged. It's
been confusing earlier too. I'll fix the code so it no longer writes it.
Instead, this is more correct..:
Error: brain M: Exporting mailbox INBOX failed: Mailbox attribute iteration
failed: BUG: Unknown internal error
The problem most likely here is that your Sieve settings aren't working for
some reason. Unfortunately the error handling code paths are buggy in v2.4.0,
so you're not getting the proper error logged. If you post your doveconf -n
output I could try to figure it out.
