I did have Usermin configured to read directly.  I have changed this so 
Usermin goes through the local IMAP server (dovecot) and Usermin seems 
to be working much better with the mail.

However, I have a new problem...

I've changed my mail location back to mbox as follows:

mail_location: mbox:~/mail/:INBOX=/var/mail/%u

This is working great with two exceptions.

First, using mozilla thunderbird as a client, I can create folders, but 
I can't create sub-folders.  Why might this be?

Second, I have Usermin configured to save a copy of sent mail in a 
folder 'Sent'. mozilla thunderbird is doing this OK, but Usermin is 
not.  It gives me the following error on the web interface:


      Failed to send mail : Failed to set IMAP flags : Error in IMAP
      command UID: Invalid arguments.



Checking through the logs, I don't see any other errors so I'm having 
trouble find out why?  The email does get delivered, but no copy is saved.

That's exactly what I'm going for.  Good to hear I can expect it to work 
fine.
