With RC and Dovecot running on the same box, an IMAP proxy isn't going
to significantly increase performance, if any. The purpose of the proxy
is to establish an IMAP login and keep it open like a desktop MUA (TB)
does, so that each client command doesn't require a login/logoff cycle
as is the RC connectionless default. With everything running on the
same box, the normal RC logon/off cycle is instantaneous. So by using a
proxy in this scenario, you simply increase daemon complexity for
little/no gain.

If you're still determined to try this proxy, check these RC settings.
Specify localhost.
// the mail host chosen to perform the log-in
// leave blank to show a textbox at login, give a list of hosts
// to display a pulldown menu or set one host as string.
// To use SSL/TLS connection, enter hostname with prefix ssl:// or tls://
$rcmail_config['default_host'] = array("localhost");
Your use of TCP 1993 suggests you're trying to use SSL. This must match
from RC to proxy to Dovecot. SSL is completely useless when all daemons
run on the same box, so use plain auth on TCP 143.
// TCP port used for IMAP connections
$rcmail_config['default_port'] = 143;
Again, it's silly to encrypt via SSL when all the traffic is inside the
RAM of the box, nothing over the wire. The over the wire security from
your browser to RC is provided by HTTPS.
// IMAP auth type. Can be "auth" (CRAM-MD5), "plain" (PLAIN) or "check"
to auto detect.
// Optional, defaults to "check"
$rcmail_config['imap_auth_type'] = plain;
Again use plain authentication. Simply using plain auth and
non-encrypted IMAP connections will speed things up slightly over using
SSL as it eliminates the cycles required for encryption.
