Key label
If your incoming mailbox is configured to require a security key, then the Key label/value pair must be present in the incoming email message. A key is required to use the Modify action. The passwords and security keys are encrypted in the AR System Email Messages form. Aliases for the Key label are Encryption Key and Encryption. An example of a Key label/value pair is Key:testKey.
