Maybe not "all", but I think nowadays the vast majority of MTAs that can
receive email use a mix of DKIM/DMARC/SPF to filter out some messages
which are deemed to be "illegitimate".  Some people maybe consider that
as separate from "spam filtering" where you rely on heuristics to try
and classify the message, but at least in theory these DKIM/DMARC/SPF
tools were sold as ways to filter out spam (they seem to be pretty at
consolidating the Gmail/Microsoft monopoly as well).
