Description of problem:
SPF permits MTAs to verify that the sending MTA is a permitted source
of mail for a given domain by checking dns txt entries.

SPF is gaining widespread adoption, including large ISPs.

For a system to fully participate, its MTA must be able to validate
SPF for received mail. Sendmail milters or patches are available to
support this.

I would like to see SPF support provided in RHEL (presumably by milter
until sendmail supports it natively)

SPF is patented, therefore there is no way to put it in.
Comment 2 Stephen Lewis 2004-11-03 12:39:52 EST
I think you are mistaken - are you possibly thinking of the Microsoft 
Sender ID, which does have patent issues. I believe Sender Policy 
Framework (SPF) is open, and has now been adopted by the IETF.
