SPF Re: fetchmail not fetching spam with invalid email address

It's not the SPF configuration that's broken, but the mail server
itself. They accepted mail with a MAIL FROM that was non-compliant[0]
and should have been rejected. It's the acceptance of mail with broken
sender addresses that is their problem.

Basically, the senders address should have been either a NULL sender
(<>) or in the format:

username@domain

They accepted mail that didn't have the domain part when they shouldn't
have done.

I never configured mail server successfully to work with my ISP, which
should tell how much I know about, but if email server has another rules to
follow, like the one above, what is the purpose of SPF?
Reading articles http://www.openspf.org/ doesn't help me.

I checked few email headers in my mailbox and I don't see many with
Received-SPF: part, so it seems that many people that know how to configure
mail servers don't find it useful.
