Behavior

You have created a rule to enforce Websafe, but the email was not delivered as a Websafe message; instead, it was sent using another encryption method. Alternatively, you have created a rule to enforce Websafe, and other emails are also unintentionally encrypted with Websafe.

Possible Causes:

1. A Higher-Level Encryption Method Was Used

Websafe serves as an encryption option in case the communication partner does not support a higher-level encryption method.

The selection of the encryption method occurs automatically according to the following logic, provided no encryption policies have been set up:

• The following order is checked to determine which encryption method can be applied to the email: S/MIME → PGP → EmiG → TLS → Websafe
• Once an encryption method can be applied, only encryption methods compatible with it are considered in the further processing (see Combination of Encryption Methods).
• Only if none of these higher-priority methods are available will the message be delivered as a Websafe message.

How to Check the Encryption Method Used

You can track whether and with which method the email was encrypted by using Email Live Tracking:

1. Open the module Email Live Tracking.
2. Search for the relevant email (e.g., by recipient and subject).
3. Check the details of the email to see which encryption method was used.

2. The Rule for Outgoing Websafe Encryption Was Configured Incorrectly

In the rule module under Email Security > Email Encryption in the tab Encryption Policies > Rules for Outgoing Emails, regular expressions should primarily be used for the entered terms in the criteria fields.

Otherwise, more complex values containing special characters may lead to undesired application or non-application of the encryption rule due to their interpretation as regular expressions.

You can find assistance on this topic in the manual article Explanation of Regular Expressions.
