Mail Server Sample Clauses

Mail Server. (a) Availability. The Company guarantees a 99.9% rolling 30 days average of scheduled availability of its mail servers. Mail server availability is defined as the clientʼs ability to send (SMTP) and retrieve (POP3) e-mail via the particular mail server. The Company does not monitor individual mail accounts, but only monitors the server as a whole. Mail server unavailability caused by denial-of-service attacks, mail bombing, and other flooding techniques is not included in uptime calculations. Mail delivery protocol (SMTP) is a “store-and-forward” type of protocol that does not guarantee immediate delivery of e-mail messages. In the case that the first delivery attempt is failed, the mail server will continue to attempt to deliver messages to the addressee according to a predefined schedule. In the case that the messages cannot be delivered for a period of time exceeding 48 to 72 hours, the messages are returned to the sender. (b) The Company calculates server uptime based on the following procedure. The Company will ping the SMTP and POP services (retrieve SMTP and POP headers) every 5 minutes with a 30-second threshold. If either service does not respond, the service is considered non-operational and is automatically restarted. If two or more consecutive SMTP or POP tests fail, the problem is immediately escalated to the Support Center. In cases where two or more consecutive SMTP or POP tests fail, the server downtime will be registered as the number of minutes between the first and the last failed tests. Downtime of less than 5 minutes in duration is not recorded. The Company calculates server uptime based on this type of server monitoring.
