When an email is sent to a recipient the email server looks to see which server handles mail for the domain using the DNS MX records. MX records specify which server(s) will receive mail for a given domain. Each MX record is given a priority (the MX level), the lowest number being the primary mail server. The primary mail server is responsible for delivering the mail to the appropriate user mailbox.
Mail delivery is first attempted to the primary mail server (indicated by the MX record with the lowest MX priority number). If that server is not reachable, then delivery is attempted to the mail server with the second lowest MX priority number. If the second lowest mail server in priority is unreachable, then the mail will be delivered to the server with the third lowest MX priority, etc.

Microsoft Exchange SolutionMicrosoft Exchange Server is an enterprise-class messaging system that provides a complete end-to-end solution for electronic messaging both within and outside of an organization. It provides a platform for users to exchange traditional email messages as well as non-traditional messages such as faxes and voice mail in a fault-tolerant, distributed capable environment that can communicate with other messaging systems across the world.
TLS SolutionTransport Layer Security (TLS) is a protocol that ensures privacy between communicating applications and their users on the Internet. When a server and client communicate, TLS ensures that no third party may eavesdrop or tamper with any message. TLS is the successor to the Secure Sockets Layer (SSL).
TLS is composed of two layers: the TLS Record Protocol and the TLS Handshake Protocol. The TLS Record Protocol provides connection security with some encryption method such as the Data Encryption Standard (DES). The TLS Record Protocol can also be used without encryption. The TLS Handshake Protocol allows the server and client to authenticate each other and to negotiate an encryption algorithm and cryptographic keys before data is exchanged.
