Why did I receive a "Read:" email message?

If you received an email message at your Indiana University account with a subject line that begins "Read:", followed by the subject line of an email message you sent, that is likely a read receipt for a message encrypted by the Cisco Registered Envelope Service (CRES); see What is the Cisco Registered Envelope Service (CRES)? The read receipt indicates that your recipient has decrypted and read the email message you sent.

If you did not send sensitive data in the message, and did not intend for it to be encrypted, examine your original subject line. If it contains the phrase "secure message" or word "confidential", CRES will always encrypt it, regardless of content; see How can I ensure that mail sent from my Exchange account to an outside address is encrypted by CRES? Avoid using those words if you do not want your messages to be encrypted.

If you do not want to receive further read receipts of encrypted messages, you must change the CRES settings for your account; see In CRES, how can I change my password or preferences? On the "Edit Profile" page, under "Preferences", uncheck Request Read Receipt: Let me know when recipients open their messages.
