Key-Exchange-Method-IMAP/EN

If the result is positive, there is no need for further action. If the result is negative, please read the following instructions.

Result positive	Anonymous key exchange is not supported
Result negativ	Anonymous key exchange is supported
Description	Your server is configured to allow connections without verifying the identity of your server.
Background	The term Cipher Suite stands for a collection of cryptographic methods used (encryption of information). This collection includes the key exchange method, digital signature, encryption and cryptographic hash functions. This combination of cryptographic components ensures a secure connection between two parties, e.g. your mail program and a server. In the TLS protocol, the Cipher Suite (cryptographic procedure) determines which algorithms are to be used to establish a secure data connection and is decisively responsible for the security of the connection.
Consequence	Your server is ready to establish very weak connections, which are vulnerable to Man-in-the-middle attacks. This can be used to read out mail content and misuse them for criminal purposes.
Solution/Tips	If Anonymous key exchange is supported is reported, disable "Anonymous key exchange" support in encryption methodology.
