Email headers
This feature might not be available for all customers yet.
Data Control rules in Sophos Email allow you to add and change email headers to select how a message is encrypted.
You can use a Data Control rule to add the following headers and change the way the encryption is applied to the messages that match the rule's criteria.
Portal Encryption without recipient authentication
You must have a license that includes Portal Encryption.
| Header | Values |
|---|---|
X-SophosEmailEncrypt-NoAuth | true or false |
If this header is set to true, the recipient receives a link to a portal-encrypted email that won't require recipient authentication to view the message.
Portal Encryption with verification code
You must have a license that includes Portal Encryption.
| Header | Values |
|---|---|
X-SophosEmailEncrypt-VerificationCode | true or false |
If this header is set to true, a verification code is sent to the sender after the portal-encrypted email is sent to the recipient. The sender must share the verification code with the recipient so that the recipient can access the email. The recipient can also generate a new verification code, which is then sent to the sender.
Expiry period
| Header | Values |
|---|---|
X-SophosEmailEncrypt-ExpiryPeriod | today, fiveDays, oneWeek, or twoWeeks |
You can set a message expiry period up to the maximum set in your account. The default maximum expiry period is 30 days, which you may have modified as part of the custom branding of your account. In the case of Push Encryption, the expiry period applies only to the registration message.
Sent notification
| Header | Values |
|---|---|
X-SophosEmailEncrypt-SendNotification | true or false |
If this header is set to true, the sender receives a notification when the encrypted email is sent to the recipient.
Read notification
| Header | Values |
|---|---|
X-SophosEmailEncrypt-ReadNotification | true or false |
If this header is set to true, the sender receives a notification when the recipient reads the encrypted email. In the case of Push Encryption, the read notification is only sent for the registration message.
