Re: Question about confidential data in emails.

[Frank Barton <bartonf () HUSSON EDU>]

This is actually a question that came up as part of our PCI process.

The 'official' response that we got to our question was that
(a) we should make sure that we indicate not to send [CHD] over email
(b) We should not process anything based on the information we received
over email
(c) we should redact and reply that we can't process it based on
unencrypted email.
(d) delete the original email
