How can I view a CRES-encrypted message sent to a mailing list?
Note: You should not send sensitive data to a mailing list, including IU List mailing lists or Oncourse Email Archive distribution addresses; lists might contain recipients you do not intend or of which you are unaware, even if you are a list administrator. To protect sensitive data sent via email, include all intended recipients on the To, Cc, or Bcc lines; at IU, use of an encryption service like CRES is required (see How can I ensure that mail sent from my Exchange or Cyrus account to an outside address is encrypted by CRES?).
An email message sent from an Indiana University Exchange or Cyrus account to an outside address may be encrypted by the Cisco Registered Envelope Service (CRES) if it contains certain sensitive data; see What is the Cisco Registered Envelope Service (CRES)?
To read the message, you would have to have registered the group email address with CRES; see How can I read a CRES-encrypted message? Each address can only have one registrant, the first person to register that address with Cisco. Therefore, if you own or moderate a list that receives a message, you should register the list address before another list member attempts to read an encrypted message.
Note: It is not always possible to register a list address with CRES. For example, IU List will discard the registration message from CRES, which is required to complete the registration process. IU List mailing lists therefore cannot be registered with CRES, and CRES-encrypted messages sent to IU List mailing lists cannot be viewed.
