I think that would reject quite a bit of legitimate mail. Any message that's being auto-forwarded from one address to another is likely to contain the "Delivered-To" header (though that header doesn't seem to be a defined standard, so it's up to each mail server to add it or ignore it). What you really need is a way to filter messages based on the content of the "Delivered-To" header (i.e. if it matches the recipient address). spamdyke is in a position to do this but doesn't currently have the capability.
