Configuring SSL for POP3 and IMAP4 Clients
To help secure communications between your POP3 and IMAP4 clients and the Exchange 2007 server that has the Client Access server role installed, it is strongly recommended that you use Secure Sockets Layer (SSL). For more information about how to use SSL with POP3 and IMAP4, see Configuring TLS and SSL for POP3 and IMAP4 Access.

When you use POP3 and IMAP4 clients, you can set authentication options, such as the ability to use TLS encryption, and configure ports for communication with clients. For information about authentication options for POP3 and IMAP4, see Configuring Authentication for POP3 and IMAP4.
