Subject: [PATCH] Dovecot: Add IMAP capabilities.
Nextcloud Mail is having issues with the following Dovecot error:
```
failed: Invalid quoted-printable input trailer: '=' not followed by two
hex digits
```
From
https://forums.cpanel.net/threads/dovecot-invalid-quoted-printable-input-trailer.648081/
it appears that some capabilities are missing. Add them.
