Hello

Your access level shows up as "Website Owner". Do you have root access to this server? If not, please contact your web hosting provider regarding this error so they can assist you. If you do have root access, check to make sure the domain name is in the /etc/localdomains file. Also, try running the following command to ensure proper permissions are set:

/scripts/mailperm $username

Search /var/log/exim_mainlog to find the specific output when attempting to send/receive emails.

Thank you.
