Yes, 2000 it was sendmail, nginx, apache, smtpd if i remember correctly; but my question is: "Could someone please point me to specific openbsd place to look for it?" > - I assume it's related to outbound mail, but even that is not > completely clear to me. No, it is the complete behaviour of dkim, dmarc, and spf. i got 0/10 at this page: https://www.mail-tester.com/ and yes, i can receive mail, but mine is considered spam! > - Did you just put a dkim txt record in DNS without any additional > configuration on your mailserver? ok: i have 2 servers: 1. managed by nsd, which obtained 9.7/10 at the same web page, not a problem; 2. vultr managed by their dns app, here i am not able to make it work correctly.
