Basara,
I did check the log and found nothing, but doing a system search for MAIL, I found a few entries. I right clicked on the entry below and it opened up the mail configuration page and I was able to configure it and saved it. However, when I try to access it from the menu, the same error appears and I have to press the BACK button to return to the admin section.
Mail Protocol:Mail: Default server mail server will be used. Make sure it is configured and able to send email with PHP mail. - default
