First of all, what versions are you using? How is it all configured? Do 
the Dovecot and Cyrus logs contain anything useful?

Your setup is a bit odd. I haven't tried this ever and doubt anyone else 
has. The proxying feature is mainly implemented with Dovecot back-ends 
in mind. In an ideal world this should work however, so there is a 
possibility that the Dovecot proxy is not working properly.

Theoretically, this setup should be possible. However, the protocol 
specification is unfortunately not always followed to the letter. Also, 
Cyrus possibly does not allow you to login with the SASL PLAIN mechanism 
(the only one supported for proxying now). This seems unlikely though, 
since the IMAP proxy does work.

Without more information I can only guess what is going on. Could you 
sniff the communication between Dovecot and Cyrus (e.g. using ngrep)? 
Perhaps, if it is not too much trouble, I can make it work...
