dovecot - Mar 2008 - IMAP storage - mail_location = maildir:~/Maildir:mbox:~/mail/

I'm moving to IMAP and trying to understand all the details of where to 
save email.  The system is CentOS running sendmail - procmail which 
delivers as:

DEFAULT=$HOME/Maildir/

I'm trying also to use Usermin as the webmail client.  I can get mail to 
deliver to $HOME/Maildir/ and I can get clients (thunderbird outlook 
etc) to view them.  However Usermin seems stuck with saving 'Drafts' 
'Sent' and 'Trash' in $HOME/mail/ as mbox and Dovecot won't
find them
even when I use the setting:

maildir:~/Maildir:mbox:~/mail/

I don't know what exact question to ask to I'll just ask for any 
thoughts on this?

Second question, different topic.  Are there problems with running POP3 
and IMAP?  I've always run POP3 and I'm thinking to move to IMAP for 
some clients so the Usermin webmail will be better 'synchronized' with 
the users inbox.

Do you have usermin set to access mail by IMAP or the default of accessing the 
mail directly on the filesystem?

On your second question, I run bothPOP3 and IMAP on the server. Some people 
with light traffic just want to get the mail to their PC, and other users want 
IMAP so they can work with their mail from multiple locations and computers.

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.
