dovecot - Apr 2020 - Bug maybe already resolved? Sieve rule does not accept special use folder names

I do not have the log file anymore from the home dir. It just complains 
that the folder Spam does not exist.

 dovecot: lmtp(xxxx): oG8YI6enmF7FIAAAI7dPvA: sieve: Execution of script 
/xxxx/.dovecot.sieve failed, but implicit keep was successful (user 
logfile /xxx/.dovecot.sieve.log may reveal additional details)

I can't tell without insight in the error message and your full 
configuration (`dovecot -n`).

So, does that Spam mailbox exist? The mailbox configuration you posted 
tells me that it is at least not created automatically once accessed.

It is a 'special use' folder, so it only appears to exist in mail 
clients. 

  # spam folders merging
  mailbox Junk {
    special_use = \Junk
    auto = create
  }
  mailbox Spam {
    special_use = \Junk
    auto = no
  }
  mailbox "Junk E-mail" {
    special_use = \Junk
    auto = no
  }
