David,

If you have the time, could you explain where the problems you mentioned 
occurred - were these incoming messages that failed at your server, mail 
sent to other than your domains that failed due to the ISP being sent 
from,....? I use the word 'failed' as a general term meaning it's  not doing 
what it's suppose to do. Will you not check incoming SPF records now, also?

I do not fault your decision, but find that a lot of people soft fail SPF 
checks, and this doesn't add to its reliability. I'm just curious, and could 
use yours thoughts on this for the future when our decision may arise to 
remove our records.

Thanks.
