Just a thought : There is a difference between what options dovecot
presents and what imapproxy present. Wonder if RC requires some other
options presented from ImapProxy that it had got directly from Dovecot.
# telnet localhost 3993
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE
STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready.
a1 logout
* BYE Logging out
a1 OK Logout completed.
Connection closed by foreign host.
# telnet localhost 1993
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ LOGIN-REFERRALS ID ENABLE
AUTH=LOGIN XIMAPPROXY] Dovecot ready.
a1 logout
* BYE LOGOUT received
a1 OK Completed
