Yep - although the bigger they are the more likely it is to be some
oddball bundled mail system that requires weeks of learning in my
experience.

With regard to SPF - my point is it trades a lot of manpower to get a
short term benefit at those mail servers that have limited SPF addresses.

In general the same effort would be better expended on methods that
would reduce spam significantly, rather than ones that are just likely
to change the forged email addresses in use.
