>I think this is a case of “knows enough to be dangerous”. https://en.wikipedia.org/wiki/Jamie_Zawinski > At Netscape, he developed the Unix release of Netscape Navigator 1.0,[4][5] and later, Netscape Mail, the first mail reader (or Usenet reader) to natively support HTML.[6] I mean, you can draw the line wherever you want, but I expect that he probably knows more about mail than the average bear.

Agreed. I said it elsewhere, but despite his technical knowledge, he appears to be a terrible admin, one that I would only being on as a junior if I was hiring. I've met (and been) this admin before, and a lot of the time it's because they stepped up, are learning on the job, and don't know what standard build/tool chains are. But when stuff breaks, it always ends up sounding like this blog post

It's not his SPF record. The forwarding he's talking about isn't the same as you hitting forward in your mail client. SPF only authenticates the first hop from the origin MTA. If you put a relay server in then you either need to disable SPF checking on subsequent MTAs or implement RFC8617. If you don't then when subsequent MTAs check *the original sender's SPF* it will fail because the message came from your relay.
