Kendra actively filters incoming Email for Unsolicited Commercial Email, or Spam. The filtering is not a full guarantee that no spam will make it into a customer's inbox, but is a good faith attempt to limit Spam. Kendra does not guarantee that all legitimate mail will make it by the spam filter. Email tagged as Spam and held on the server is stored for 5 days, then deleted; if you are missing a Email contact abuse@kendra.cc with the senders Email address and approximate date so the held Emails can be checked. A method will be supplied to allow blocked Email to reach customers on a per Email address or per top level domain basis. A method will be supplied to report Spam that makes it through the filter, but no guarantee is granted that the mail will be stopped. Kendra is not responsible for email that is stored on the mail server(s). Customers are expected to download Email off the server. If a customer is using Web Email to read and maintain their messages they must keep the storage allocation below 50 megabytes.
