Does anyone participating in this discussion group know of any work done using the SMTP header field "Encrypted", which shows up on pages 24 and 25 of RFC 822? A little background, we are currently working on trying to send an SMTP mail message with a CRC based on the entire message (mail header and text). Since mail headers can change, and usually do, does anyone know how it would be possible to CRC an entire message and pass the message through the internet and have the CRC remain valid? Could this be done without changing SMTP requirements to recalculate a new CRC after each header line is added? It is possible to CRC just the text of a mail message and trust the mail header to only contain network relevant information, but that is not desirable. Thanks for any help. +---+ Id: Lance Browne |\ /| Net: lance@logicon.arpa | ? | XXX: |/ \| USPS: 4010 Sorrento Valley Blvd, San Diego, CA 92121 +---+ Phone: (619) 455-1330
