Email Encryption- End-to-End TLS Encryption Service
MessageLabs hosted Email Boundary Encryption service uses TLS encrypted tunnels to establish secure end-to-
end encryption between your mail server and your partners’ or clients’ mail servers, preserving
confidentiality of all content contained within email communications. Every email sent or received via this
channel securely encrypted, but the application of encryption remains totally transparent to both sender
and receiver.
MessageLabs Boundary Encryption service is interoperable with market-leading mail servers, including
Microsoft Exchange, Lotus Domino and Sendmail.

destination. Our Email Boundary Encryption service provides a cost-effective, affordable method of
