I think that this needs some change:

 # From Spam folder to elsewhere
  imapsieve_mailbox2_name = *
  imapsieve_mailbox2_from = Spam
  imapsieve_mailbox2_causes = COPY
  imapsieve_mailbox2_before = file:/usr/lib/dovecot/sieve/report-ham.sieve

When a message from Spam is moved to Trash then the report-ham.sieve is
being executed.

Can we add an exception for the Trash folder?

Thanks
