Your email can be read via WebMail by going to
http://www.yourdomain.com/webmail
The username is the complete email address i.e. username@yourdomain.com and the password is what you set in cPanel when the account was added. If you cannot access webmail because you are behind a firewall i.e. from work, please email us and we will install a workaround script for you that will enable you to access the email/webmail.
