Yes, this app does not work anymore since Thunderbird 60.xx. The last working version was 0.3.1, after which the author started working on a standalone project that doesn't seem to work with CRAM-MD5 dovecot and other encrypted authentications. Until Sieve will work with Thunderbird again, we will grow claws :)) ( claws-mail.org)
