I finally upgraded my personal web server and switched to postfix for the first time. Sending test emails to Yahoo and GMail work just fine. However, GMail complains about what's in the title. I've never had that issue before when I was using sendmail. The raw email says spf, dkim and dmarc all pass. Both raw emails look the same with the same "d=" and other things.
The interesting point is that, if I send an email as root, there is no complaint.
I even tried the AI things which were no help except for X's Grok which admitted it doesn't see anything wrong and doesn't understand why there is an error.
I've spent too much time trying to wrap my head around 20 tabs open in my browser and still haven't found a reason or a fix. Does anyone recognize this problem?
