All mail sent to the account provided by the Center will first be processed by the anti-spam system; then, a copy will be saved on the mail reporter (as insurance in case of a false positive). The user may login to the mail reporter any time to manage (resend, change spam status, or report to vender, Cellopoint) all mail (including valid, spam, and virus mails) received within the past one year. The user can customize her/his own blacklists and whitelists to avoid blocking mail from important senders. For details, please refer to Reference Information: End-User Guide.
