Я не могу заставить SpamAssassin начать

Когда я пытаюсь запустить SpamAssassin, я получаю сообщение об ошибке:

Job for spamassassin.service failed because the control process exited with error code.
See "systemctl status spamassassin.service" and "journalctl -xe" for details.

Systemctl показывает следующее:

spamassassin.service - Perl-based spam filter using text analysis

Journalctl -xe says mostly that dovecot requires privileged execution.
