Mail security

To provide secure message transfer among clients and servers, the IBM® Domino® mail server supports name and password authentication and Secure Sockets Layer (SSL) for SMTP mail routing, IMAP, and POP3 access, and supports Notes® encryption when routing mail over Notes® routing.

To encrypt and sign messages, IBM® Notes® clients can use Notes® encryption with User ID files and public-private keys or Internet mail security with X.509 certificates. Internet mail clients can use X.509 certificates.
