Interesting history and analysis of SMTP’s history. How can we prevent fedi and other open protocols from suffering the same fates?
My most recent ISP does CGNAT. They don’t hide it, it’s mentioned in their support pages. A quick email is all it takes to switch you over to an open address though.
Anyway I’ve got a $5/mo server with akami that looks after my email and it’s associated domain.
It took about three hours of following a guide to set up DMARC and etc etc and it works unobtrusively, and is about ten times faster than my old ISP IMAP account that I had for about twenty years.
Do you have a link to the guide by any chance? I might try it again using one of my throw away domains as a test.
It was one of LinuxBabe’s guides - this one:

There is a more recent one that uses a shell script to install all the bits and pieces but I prefer to do it myself so I’ve got at least some idea of how all the pieces work.
