Whenever you need to send mail via SMTP or download it with POP3 Rebex POP3/SSL for .NET/.NET CF will provide the required infrastructure. It allows you to retrieve, create, load, process, save and send e-mail messages in MIME format using a simple yet powerful interface, with no need to understand the complexities of MIME format. And for advanced users, there is a powerful low-level MIME library as well.

Rebex POP3/SSL for .NET/.NET CF also enhances the standard SMTP and POP3 protocols by utilizing the well known and widely used TLS and SSL protocol. TLS 1.0 and its predecessor SSL 3.0 provide strong authentication, integrity and confidentiality for you communication. This is achieved by using RSA or DSA public key cryptography to authenticate the server (or even the client) and to negotiate the encryption method and symmetric keys to be usedto encrypt your data.

And there is more - S/MIME. This makes it possible to sign mail messages using an X509 certificate, and validate signed messages to make sure they were really send by the sender and not modified during the transit. Also, message encryption is available.
