Changes since 3.12.0

STARTTLS changes

The industry is deprecating STARTTLS (aka opportunistic TLS) in favor of implicit TLS over a dedicated port. STARTTLS is now disabled by default.

Installations that need to service clients that use opportunistic TLS should enable the allowstarttls imapd.conf(5) option for the services that need it. For example, for a service configured with the name imap in cyrus.conf(5), set imap_allowstarttls: on to enable STARTTLS.
