* CVE-2021-29157: Dovecot does not correctly escape kid and azp fields in
JWT tokens. This may be used to supply attacker controlled keys to
validate tokens, if attacker has local access.
* CVE-2021-33515: On-path attacker could have injected plaintext commands
before STARTTLS negotiation that would be executed after STARTTLS
finished with the client.

- imap: SETMETADATA could not be used to unset metadata values.
