Optional TLS

[OBATA Akio]

Cyrus IMAP supports both (plain port & SSL port).
In plain port connection, you can use STARTTLS command and 
change to TLS (SSL) connection.
IMAP c-client library (used by PHP imap extension) support
TLS, but PHP don't support. So, connection is failed.

I don't now TWING, but probably do like a
 imap_open("{localhost:143/imap}INBOX", "username", "password");
change to
 imap_open("{localhost:143/imap/notls}INBOX", "username", "password");
or, change your configuration to do so.
