At present, the problem is that with Thunderbird and other clients, The client run as normal. But Evolution can't get new messages or Suscription list.
Capabilities on Courier and Dovecot are differents, but when a connection is proxied to Courier, Courier print the Capabilitites.
Even though capabilities are sent to client on login, there's no guarantee that the client actually uses them. I think Evolution might be one of the clients that just ignores any updated capabilities.
What capabilities before login does Dovecot report? Have you set imap_capability setting? Maybe the problem is that Dovecot has LITERAL+ capability, which Courier doesn't support, and Evolution doesn't realize that it won't work after login. Try setting:
imap_capability = IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE
