    It also contains a small POP3 server, and supports e-mail in either the maildir or mbox format. The SQL
    drivers and authentication plug-ins are provided as subpackages.

    * dovecot: improper NULL byte handling in IMAP and ManageSieve protocol parsers leads to out of bounds
    writes (CVE-2019-11500)
