Problem Using IMP Web Mail reading interface

Hello,


I recently rebooted my Suse LInux 7.1 box, then tried checking mail via
http. I was able to pull up the login interface, but when I typed my
username and password and clicked "log in" it hung and eventually failed.

I am thinking that this is because imapd was not started ? I tried started
Imapd manually and got the following error;


admin@mail:/var > /usr/cyrus/bin/imapd
* BYE Fatal error: can't read mailboxes file


I have verified the permissions, user (cyrus) and group (mail) settings.
They are appear to be correct. I also verified that the mailboxes file
isn't corrupt and that the mailboxes file is in the correct place (as it
has always been). 

Any Ideas?

Cheers, 

Carlos.
