If it can be confirmed that either A) my end is broken, or B) a remote end is broken, I will be content, and can continue with other work. My mind will rest at ease if someone, with known bounce-no-mbox enabled, can: - provide me off list (or test for themselves from a remote location) a list of valid, and invalid recipients within their own domain's email infrastructure. It doesn't even matter if you specify which are valid and which ones are not - create a temporary account on Hotmail (or from a sympatico.ca email address, using whatever outbound servers they specify) send a message to the same recipients as requested above. - in the case that you don't want to provide the addresses, and want to test internally, inform me of the overall result - in the case that I receive the addresses to test from my location, provide me with the results of the Hotmail test so I can compare results If this is happening to other ops along with myself, I can justify it to my users, and I can justify it in my own mind. If this is a locale specific issue to my own network, then I need to know that, as I obviously have work to do. Thanks to everyone again. Steve
