I was hoping to easily find the following here.

Forums that can mirror forum posts by email.

Forums that allow posting by email.

Forums that accept posts (mirror) from an NNTP server.

Forums that copy forum posts (mirror) to an NNTP server.

Not necessarily a usenet server. Some forum software have their own newsgroup server.

Forums that include most/all of the above are rare. I don't want to search 50+ forums to find what a "search" should have produced in a matter of seconds.

I sure hope someone here can improve the search criteria.
