Thanks Paul. I'm configuring using the Admin plugin. I looked at doc/presets.txt.
With those Dovecot settings, I get that error:

ERROR: Could not complete request.
Query: CREATE "Trash"
Reason Given: Unknown namespace.

The key value seems to be "Default Folder Prefix" (default_folder_prefix). If it is
set to <none> (empty string) as specified for Dovecot in doc/presets.txt, I get that
error. But if I change it to what I used for Courier, INBOX., then everything seems
to work. This is what I have now:

 IMAP Server Type: Dovecot
 IMAP Folder Delimiter: detect
 Default Folder Prefix: INBOX.

I don't understand why doc/presets.txt Dovecot settings give me that error, so even
though things appear to work with different settings I don't know if they are
optimal.
