- Karl,
- It is MUCH EASIER to forge BITNET mail than SMTP, so SMTP is not any
- worse than what you all apparently continue to use. Use the Privacy
- Enhanced Mail (PEM) specifications and build a mail envelope that
- provides the security properties you need outside of the SMTP issue.
- SMTP is probably not a problem per se, so the PEM approach makes
- sense. The RFCs are online at the usual archive sites.
