is RFC 5465 (IMAP NOTIFY (https://tools.ietf.org/html/rfc5465.html) supported in 3.0 as stated at
Per RFC 5465 page 7, the server-side support is announced with “ S: * OK [CAPABILITY IMAP4REV1 NOTIFY]”. The CAPABILITY
answer is generated in imap/imapd.c using “static struct capa_struct base_capabilities” in capa_response(). The
latter contains no code to generate NOTIFY.
Moreover, the event_notifier in imapd.conf suggests utilizing it for EVENT NOTIFICATIONS,but the possible options for
notifyd(8) https://www.cyrusimap.org/imap/reference/manpages/systemcommands/notifyd.html are null, log, mailto, zephyr
and external: none of which is applicable to IMAP NOTIFY as substitution of IMAP IDLE.
That leaves me with the impression that the documentation is misleading about IMAP NOTIFY support.
