I offer as exhibit A to support this the fact that the OP said that, and I quote, "I got 10/10 on mail-tester.com." I suspect that while he *thinks* he has everything set up correctly he, in fact, does not. I can't imagine that any one of us here would rely ons a public free tool such as mail-tester which, while cute, what with its little boat rowing across the screen as it crunches your stats, very, very often yields false positives (meaning "your email set up is great! 10 out of 10!" when it is not). Both with customers who come to us and say "but..but.." and in our own testing, it became very clear that these sorts of services (mail-tester being but one, so not to pick on them) test, for example, for the *existence* of an SPF record, but not the *content* of an SPF record. We've even had people come to us with "10/10" scores who had *multiple* SPF records, and other issues with various DNS records. This makes sense, because these services, which are free, are not putting human eyes on those records, only counting the very existence of them as proof of adequacy in set up.
