If your first-hop router is down, how will that work? If your ISP's gateway router is down, how will that work? If the routes to your network segment are flapping enough to make TCP connections break/time out, how will that work? If your ISP is filtering outgoing STMP, or your recipient's ISP filters SMTP from known consumer IP pools, or you end up on a popular black hole list for these or any other reason, or 100 other things, how will that work? Answer: it won't. Urgent + e-mail = fail (not guaranteed fail, but a much higher chance of fail than you want with something that's urgent). -- Derek D.
