There is no such 'official' list. Each/any site which does such checks
and has a list, makes that list up entirely on their own.

If this is in respect to some specific site/DNSBL which is performing
tests, and referring to them by number, you will have to refer to that
specific sites documentation to determine what tests they use and how
they are numbered, if they are referred to by number.

These terms are by definition most decidedly NOT 'layman's' terms. They
are specific technical terms used within the field of expertise known by
some as "Internet SMTP email".

If you described something as "forged envelope-from address using domain
literal format" to your average "layman", all you'd get would be a
strange look.
