David,

You keep harping on the fact that SMTP has been working the way it  
has for 20 years and to change any facet of it that has the potential  
to throw away what is allegedly good email should be done away with.
The fact of the matter is that when SMTP was developed 20 or so years  
ago we didn't have the problems of forgery that we do today. We also  
didn't have the problem of malware and junk mail either. Do you  
advocate that the inclusion of tools like Spamassassin and ClamAV in  
the email process should be discarded as well?
On my system, that does check for SPF, Spamassassin and ClamAV are  
responsible for more ligitimate email be discarded than SPF is. As a  
matter of fact SPF has never rejected a legitimate email, ever!
David, I'm afraid your living in denial if you think that any changes  
in the SMTP protocol that requires a change in our own behaviour and  
expectations are unacceptable and not to be tolerated. You have a  
choice. You can either change your expectations and behaviour or  
accept the fact that your email will soon be accepted by fewer and  
fewer email servers. Since that's the case, you may as well give up  
now and find yourself a cave in that desert to crawl into now.
