EMAIL BUGS - SERIOUS PROBLEM WITH LAST UPDATE

I have this message from my webmail and folders inaccessible (nothing on left just inbox) !!!

System CENTOS Latest release
Virtualmin pro

Error
An error occurred listing mail in this folder : Failed to login to POP3 server : Internal error occurred. Refer to server log for more information. [2009-04-02 18:22:50]

Webmin detected that the https://XXXXXXXXXXXXX program was connected starting from an unknown address, it occurs that it is apart from the Webmin server. This can be an attempt to trap your server with the purpose of carrying out a dangerous order.
If your browser does not send the Referer header needed, you can turn off this check as follows :
Login to Webmin normally.
Go to the Webmin Configuration module.
Click on the Trusted Referrers icon.
Check the Trust links from unknown referrers box, and click Save.
Alternately, you can configure Webmin to allow links from unknown referers by :
Login as root, and edit the /etc/webmin/config file.
Find the line referers_none=1 and change it to referers_none=0.
Save the file.

Thanks
