    * CVE-2019-3814: If imap/pop3/managesieve/submission client has
      trusted certificate with missing username field
      (ssl_cert_username_field), under some configurations Dovecot
      mistakenly trusts the username provided via authentication instead
      of failing.
    * ssl_cert_username_field setting was ignored with external SMTP AUTH,
      because none of the MTAs (Postfix, Exim) currently send the
      cert_username field. This may have allowed users with trusted
      certificate to specify any username in the authentication. This bug
      didn't affect Dovecot's Submission service.

    - pop3_no_flag_updates=no: Don't expunge RETRed messages without QUIT
    - director: Kicking a user assert-crashes if login process is very slow
    - lda/lmtp: Fix assert-crash with some Sieve scripts when
    - fs-compress: Using maybe-gz assert-crashed when reading 0 sized file
    - Snippet generation crashed with invalid Content-Type:multipart
