Yes.. Anti SPF People have always said look at this..
There are many counter-options to those expressed on that website which are
also very valid.
If you are not 100% sure your users will send only from the Specified SPf
then use ? not - and then you can use other mechanims (ie rate higher for
"anti-spam" )(not that SPF is designed to stop spam).softfails than none
etc)
DomainKeys.. yes is gaining.. but even some YahooGroups Signed messages
(coming from yahoogroups) even a year ago Failed DomainKey checks.. doh..
Many Large Providers have SPF records. Microsoft , AOL, Ebay, Amazon, Paypal
.....
I won't go any futher as I'll already by now gets flamed...
Thanks
