Not to mention the inbound mail relays to manage bounces and feedback loop complaints (they appear to be using Google based on the MX settings for flyertalk.com).
There is no intermediate issue. All those servers are under a single administrative management domain. It is up to IB to sort that out. And I am pretty sure that is where the problem is. You are right that the mx records point to Google, but as IB is contracting with Google for this, IB is the one that needs to sort out the problem or switch away from Google. If indeed that is where the problem is.
Then you have the intermediate hops, whether it be via one of the internet backbone providers like ATT or L3 or something smaller, and then you have the infrastructure at your receiving mail host. Yahoo is notorious for not receiving all email, and other mail relays have filters that can be content or reputation based.
Not sure if you are familiar with how the Internet works, but backbone providers like L3 do not rewrite mail headers in the core of their networks. Plus it is pretty obvious if you read this thread that the problem has nothing to do with things outside of IB. Please go back and read the posts regarding forum updates.
Sorry to pop your bubble - email isn't as simple as many think.
Right back at you with the bubble popping. Actually mail is pretty simple if you know how it works.
With that said, I'm still receiving emails.
Can you confirm you are receiving Flyertalk forum updates? That would really be news. Otherwise, that's not what the problem is.
