What exactly is complicated about it? It's easier to implement than any
spam filter I've ever seen. I do a dns query, get the ip addresses out of
it and match them to the caller's IP address. If they match I accept the
mail, if not I drop it on the floor.

Yes:
1) it's complicated
2) no-one I trust has yet said
"it probably works for the following reasons".
Therefore, until this changes, as far as I'm concerned,
it doesn't work.
Also, as an aside, the SMTP standards contain varioushave these vague
admonitions
