    Magento installed on Unbuntu has mail issue. sudo vi /var/mail/www-data displays the following error:

    Code:

    Is it possible to isolate the issue from the above error details?

    Hello :)

    Could you elaborate on how this relates to cPanel? For instance, is this happening on a cPanel server?

    Thank you.
