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
