Thanks Ken That has solved my problem on the proxies they are now authenticating and passing on user logins
However the LMTPproxyd still has errors. auth.log on lmtpproxyd Jan 28 21:52:49 cetcb01-02-10 lmtpd[25675]: sql plugin trying to open db 'imapUsers' on host 'cyrus_sql:mysql' Jan 28 21:52:49 cetcb01-02-10 lmtpd[25675]: sql plugin Parse the username cyrus Jan 28 21:52:49 cetcb01-02-10 lmtpd[25675]: sql plugin try and connect to a host Jan 28 21:52:49 cetcb01-02-10 lmtpd[25675]: sql plugin trying to open db 'imapUsers' on host 'cyrus_sql:mysql' Jan 28 21:52:49 cetcb01-02-10 lmtpd[25675]: No worthy mechs found imapd.log on lmtpproxyd Jan 28 21:52:49 cetcb01-02-10 lmtpd[25675]: lmtpengine do_auth: sasl_client_start failed (SASL(-4): no mechanism available: No worthy mechs found) Jan 28 21:52:49 cetcb01-02-10 master[25634]: process 25675 exited, status 75 Jan 28 21:52:49 cetcb01-02-10 master[25634]: service lmtpd pid 25675 in BUSY state: terminated abnormally imapd.log on backend Jan 28 13:51:31 cetcb07-01-09 lmtp[30694]: accepted connection Jan 28 13:51:31 cetcb07-01-09 lmtp[30694]: connection from cetcb02-02-10 [10.18.13.95] Jan 28 13:51:31 cetcb07-01-09 master[30706]: about to exec /usr/cyrus/bin/lmtpd Jan 28 13:51:31 cetcb07-01-09 lmtp[30706]: executed Should I change the conf file for imapd cyrus to start TLS on lmtp?

You are correct, if you are only using plaintext authentication, then you'll need the frontend to use STARTTLS on the backend. Unfortunately, support for this is not in the 2.1 series. You can either upgrade to 2.2.3 or try to backport the STARTTLS patch to 2.1.16.
