So, people get lots of spam. Much of this spam is forged to make it look like it's coming from themselves, or someone else at their domain.

Thus, many IT departments seem to come up with the clever idea: "We shall reject mail that appears to be from foo@ourdomain.com, which is being delivered to foo (or bar) @ourdomain.com, but which is coming from some external mail server." I mean, this looks like a no-brainer, right? Why would internal mail ever be trying to come from an outside source, unless it's Evil?
