So let's be clear: If you have time-sensitive communications that need to be delivered immediately, reliably, you should almost certainly not be using e-mail for them. Just becaue your mail client is able to hand off your message to your outgoing mail gateway in no way means that it is guaranteed to be delivered quickly, or even at all... Delivery may still fail or be delayed due to intervening mail servers' load, connectivity, hardware failures, botched configuration changes, etc., and in all likelihood you won't know anything about it. If you can not accept this, you must not use e-mail to deliver your message. If you can accept this, then having the message queue locally on your machine is less of a risk than having it queue on any other SMTP node along the way, because you can actively detect such problems and potentially do something to fix them, whereas in all other cases you simply can not. And the reality is, once your networking and your MTA is configured correctly, as long as your internet connection is working, your mail will go out, and will continue to go out so long as you don't muck with things and subsequently botch them. If you do make subsequent changes, of course you will need to test them... -- Derek D.
