dovecot - May 2003 - help: The current command did not succeed. The mail server responded: Invalid mask.

Am tryin to move from uw-imapd to dovecot, using dovecot ver 0.99.9.1-1 
on debian.  Using Mozilla Mail v 1.3 currently using mbox format.

I made some test accounts and they seem to be working fine, but my older 
existing accounts give error messages whenever I connect or subscribe to 
  mailboxes within them.  The message that appears on the client is:

"The current command did not succeed. The mail server responded: Invalid 
mask."

it appears three times in an alert box (on windows) then everything 
seems to work.  There are no messages in any of the mail logs in 
/var/log which would indicate a problem.

The test accounts I created don't have this problem so I tried renameing 
the home directory, deleting the user, then recreating the user. 
However even with a new homedir the problem remains unchanged.  I have 
verified that the permissions in ~/mail and /var/mail are set 
identically for working and non-working users.

Thanks in advance for any advice,

Mozilla is probably remembering some old settings from uw-imapd. I'm not
sure what exactly, since they should have pretty similiar settings.
Maybe anyway related to handling ~/mail or namespaces in general.

That error happens anyway if client tries to use absolute file paths
(/path, \path, ~/path/) or tries to use ../ or ..\ in the path. '\'
checking isn't actually really needed, but I thought I might as well
prepare for future VMS/Windows port :)

Instead of giving the error, I could also just make Dovecot ignore that.
I'm not sure if it'd be better..
