Has anyone ever set up TMDA to proxy email for an entire domain? My goal is to figure out a setup which will employ TMDA as a mechanism for deterministically identifying when a bounce legitimatately came from my domain and when it's been forged. In this case, I would not use the C/R features of TMDA.
I currently use TMDA (including C/R) on my personal account. And I can ID legit bounces from illegit bounces by tagging the sender address in all outgoing email with a dated address. Legit bounces will be sent back to a legit dated address and will be allowed to pass. Illegit bounces will be dumped. I want to see if it's possible to scale this to a much larger group of people (everyone in an entire email domain) without requiring that everyone in that domain individually run TMDA. In other words, I want to transparently run TMDA on all email leaving and entering my domain. And the only thing I would tag is the outgoing sender address so that I can deterministically identify legitimate bounces and drop illegittimate ones. This would actually be helpful to the anti-C/R crowd. They could use TMDA to drop incorrect challenges, and allow correct challenges. It seems like this should be possible? Has anyone ever done it? Does anyone have any thoughts on if/how it could be done? Or am I way off in trying to use TMDA to do this? Constructive feedback is appreciated.
