That isn't the question I asked. I answered -that- question in one of my earliest posts: if the From field is not user@host.domain. That was right before I pointed out that this is a religious debate. [...] | Will that incorrectness ever cause problems? Potentially, yes. Received headers will tell you the route a message has taken, but it will not necessarilly tell you anything about the humans involved. | A wrong guess in the other direction can cause problems. "Correct" isn't | always the best thing to be. A wrong guess in the other direction will not cause problems unless someone violates RFC 2822 and misuses Sender. -- Rat \ If Happy Fun Ball begins to smoke, get Minion of Nathan - Nathan says Hi! \ away immediately.
