Has anyone created hooks in MTAs so that they automagically sign outbound email, so that you can stop forgery spam via a SRV DNS record?
Take a look at DKIM (Domain Keys Identified Mail) which does precisely that. There is an IETF working group for it, and it is presently being deployed by people like Yahoo, Google, and others. There's support for it in SpamAssassin as well as a Sendmail milter.
Go look at <http://www.dkim.org/> for many more details. Jon --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
