I am trying to make a connection to office 365 through stunnel so the traffic will be encrypted as 365 will only parley with encrypted traffic and authentication.<br />
<br />
I have got the config file to the point where all it wants is authentication &quot;to prevent MITM attacks&quot;. <br />
<br />
Does anyone know what the syntax is for adding in a username and password in for Stunnel to speak to 365.<br />
<br />
Any other tips about how to get a pop3 collector to speak to 365 with SSL and user/administrator authentication in the 365 tenant would be much appreciated.<br />
<br />
Thanks,

Experts,

I am trying to make a connection to office 365 through stunnel so the traffic will be encrypted as 365 will only parley with encrypted traffic and authentication.

I have got the config file to the point where all it wants is authentication "to prevent MITM attacks". 

Does anyone know what the syntax is for adding in a username and password in for Stunnel to speak to 365.

Any other tips about how to get a pop3 collector to speak to 365 with SSL and user/administrator authentication in the 365 tenant would be much appreciated.

Thanks,

Encryption is the process of encoding messages or information in such a way that only authorized parties can read it. In an encryption scheme, the intended communication information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted. For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm. An authorized recipient can easily decrypt the message with the key provided by the originator to recipients, but not to unauthorized interceptors.

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.

HTTPS is a protocol for secure communication over a computer network which is widely used on the Internet. HTTPS consists of communication over Hypertext Transfer Protocol (HTTP) within a connection encrypted by Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL). The main motivation for HTTPS is authentication of the visited website and to protect the privacy and integrity of the exchanged data. HTTPS is widely used for protecting page authenticity on all types of websites, securing accounts and keeping user communications, identity and web browsing private.
