How can I read a CRES-encrypted message received at my Imail or Umail account?
When an email message is encrypted by the Cisco Registered Envelope
Service (CRES), it is encrypted for the recipient's email address. If
you have an Imail or Umail account, messages sent to you at
automatically be forwarded to you at
firstname.lastname@example.org . This means that the
address for which the message is encrypted is not necessarily the
address in the message's "To:" line. You will need to examine and
possibly adjust the address on an incoming CRES-encrypted message in
order to read it.
Note: The directions in the document address the situation when an Indiana University student receives an encrypted message sent from an IU email system (e.g., from a faculty or staff member's Exchange or Cyrus/Webmail account). Other situations might require different solutions, including:
- You receive an encrypted message from a non-IU source, such as an IU Health hospital; these messages will have been encrypted by that source's systems.
- You receive an encrypted message from an IU source that was a reply to or a forward of an earlier message, or was composed and sent from the CRES system; these messages will have been encrypted at Cisco, not at IU.
- You receive an encrypted message that has been autoforwarded, either from IU or from another account, or by your email client. See At IU, how do I forward my email?
In these cases, follow the instructions in How can I read a CRES-encrypted message? If you cannot view the message, see Why can I not read a CRES-encrypted message? If you have forwarded your email, try to determine the address to which the envelope was originally sent, and use that address to register and read the message.
Recipients of encrypted messages will receive an email message stating
"You have received a secure message", with an attachment named
securedoc_20111027T114704.html ). This
securedoc file is the Cisco Registered
