Al, fwiw, I've confirmed at some point within the past couple of years - directly with Brandon Long of Google - that, yes, Google does have this extra after-connection filtering, where a message can potentially be spam filtered even though the sender's mail server received a "250 OK"

I've seen it happen perhaps twice in twenty years, from what I can non-scientifically recall. 99.9% of the time we've had somebody complain they can't find the mail in their Gmail account, it is because it's in their spam folder. I'm not particularly worried that there's some new outbreak of

I've seen Microsoft do that very thing many times over the years, accepting an email but never delivering it. I have to admit, I have not once witnessed this with Gmail. Given how much volume we do where customers bring their own domains, I would find it strange to have not run into it, if it

If you can take the activist hat off and think like an average person with average objectives, Google is the right answer. There is nothing wrong with suggesting this. There are pros and cons. As a grown up, I understand that everything is a trade off. But for most people, Google is the right

This is in fact how they do it, and it is quite objectively wrong. SPF is only useful when checking the connecting IP, but since they're not receiving the mail they miss out on that transaction. Reasonable logic would dictate that one should give up attempting to check SPF at that stage or, at
