Messaging overview
The IBM® Domino® mail system has three basic components: Domino mail servers, Domino mail files, and mail clients. The Domino mail server is the backbone of an organization's messaging infrastructure, acting both as an Internet mail server and an IBM Notes® mail server. Domino provides standards-based Internet messaging through its support of the Simple Mail Transfer Protocol (SMTP), Post Office Protocol version 3 (POP3), Internet Message Access Protocol (IMAP), and Multipurpose Internet Mail Extensions (MIME). At the same time, Domino supports Notes mail through the use of Notes routing protocols -- Notes remote procedure calls (NRPC) -- and the Notes rich text message format.
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.
