If indeed that is where the problem is.
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.
Right back at you with the bubble popping. Actually mail is pretty simple if you know how it works.
Can you confirm you are receiving Flyertalk forum updates? That would really be news. Otherwise, that's not what the problem is.
You're "pretty sure"... well that helps us.
Any mail relay server can be configured to rewrite mail headers and I have seen it happen in practice.
Email
should be pretty simple, we agree on that. Once you start to have multiple services to properly manage load distribution and delivery, problems can and will pop up. I've seen this multiple times over the past 7 years in my role as a technical email architect.
I have no info on where the problem actually exists, but you should know it's not as simple as just looking in one config file and tweaking one number. That was the tone of the messages I was responding to, and I wanted to dispel that thought.
I've never used forum updates (daily? not very useful for me...) - just signed up for one to see if it worked. Will report back.
