David, >> What happens in challenge/response when you have two challenge/response mechanisms talking to each other, each wanting a challenge/response to a challenge/response? Table tennis? << The challenge (or any other alerts/bounce messages) should be sent by from a "service" account (e.g., [EMAIL PROTECTED], [EMAIL PROTECTED], etc.) or even an unattended (non-existing) account - which is set up to NEVER return "automated" emails. So - even if the other side were to send an automated email back - at WORST it would end up in the service account but not lead to an endless "confirmation request loop". Best Regards Andy Schmidt
