Encryption policies

Email Encryption allows you to define encryption policies for the email traffic of your domain.

Upon activation of Email Encryption (see Activating Email Encryption), you can check which encryption methods are supported by your communication partners (see Checking the Encryption Capability of Communication Partners).

With this knowledge, you can choose from a series of encryption methods (see Encryption Methods) and activate encryption methods for your domain (see Activating Encryption Methods). Additionally, you can set references to the employed encryption method in the subject of your encrypted emails (see Referring to Encryption Methods in the Subject). The encryption methods are processed in a fixed order (see Order of Encryption Methods) and can be combined with each other (see Combination of Encryption Methods).

With the activated encryption methods, you can define rules for the encryption of the incoming and outgoing email traffic of your domain (see Adding a Rule). The rules are ordered according to their priority and are processed in that order (see Rule order). You can edit (see Editing a Rule), activate (see Activating a Rule) and deactivate (see Deactivating a Rule) existing rules. As soon as a rule is no longer required, you can delete it (see Deleting a Rule).

You can also use keywords in the subject of outgoing emails to trigger actions for S/MIME encryption and/or S/MIME signing of emails (see Using Keywords in the Email Subject).
