just wondering if anyone is adopting the openspf standard and how many email servers are using it.
Theres no numbers for how many servers are using SPF records, however that number would be quite high.
Hotmail, etc actively check for SPF records so you can be sure most things that send email will have a SPF record. For example even sitepoint has an SPF record

I also had a customer forward me a message from Yahoo mail that said some email messages could not be delivered due to the SPF record being absent.
It's taken 4 or 5 years to gain acceptance from some of the major providers, but I think it is safe to say that the adoption of SPF as a requirement will continue to increase, so best to get those SPF records in order

not sure if I did the wizard right but I got
example.com. IN TXT "v=spf1 mx -all"
is that ok, will that work?
