        Hello,
3.12.x uses concurrent connections to an IMAP account, which are there 
to help with response times. I would try to disable it on your 
machine, you've everything stored locally, after all (as you said in 
other messages in this thread). You can do that in Edit->Preferences-
> Mail Accounts-><IMAP account>->Edit->Receiving Options tab-
> Connection to Server section. Set the value to 1, which is what 
3.10.x used. Then, just in case, close & run Evolution. On the other 
hand, it doesn't explain the error, because the concurrent connections 
are using different streams.

I would also discourage to connect Evolution directly to Courier's 
Maildir structure. Evolution has its own tweaks there, thus better to 
not mix it.
        Bye,
        Milan
