Binary packages in https://repo.dovecot.org/ Docker images in https://hub.docker.com/r/dovecot/dovecot Aki Tuomi Open-Xchange oy --- * managesieve: managesieve_max_line_length setting is now a "size" type   instead of just number of bytes. This allows using e.g. "64k" as the   value. - lib-sieve: When folding white space is used in the Message-ID header,   it is not stripped away correctly before the message ID value is used,   causing e.g. garbled log lines at delivery.
