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
