The email confirmation I received had this as a header from protonmail.com:

This email has failed its domain's authentication requirements. It may be spoofed or improperly forwarded. Learn more

It worked fine, but I thought you should know.

Yeah, there's a few things going on here with the ones I've received so far -

  • no dmarc for the subdomain (lemmy.sdf)
  • no spf record for the source (205.166.94.11)
  • no dkim

I'm sure it's early times, but this'll end up in the spam folders of a ton of mail services with the header as it stands today.

Indeed. Currently all emails from this instance have been landing in my spam folder.
