Ah, that clears that up then - but leaves me confused, why (or when) is
it important to check 2821 addresses?

SPF checks 2821 addresses. It makes no assertion about 2822 addresses.
Some would call 2822 address fakes "phishing", not forgery.
For 2822 checking, you should look at PRA (aka sender id). But there
are serious caveats with using it, so be careful.

Hello.
If SPF only checks the envelope from address, how does it prevent
forgery?
i.e. how does it prevent a user getting an email From:
person(_at_)bank(_dot_)com?
