It has been implemented at ISP server level so you don't get much choice
about it. If you want your emails to get through corporate firewalls you
really need to have correctly configured SPF records on your domain.

It isn't quite rocket science but the system is tightening up now.

It caused people a lot of grief last month and was one of the reasons
that HMRC backed off their usual £100 extortion for late filing. Too
many accountants and client emails were going missing finalising info.

My own accountant was off sick with Covid for good measure.
