When I am done, I can suspend incoming mail temporarily at the firewall, drop the mb server, then reconfigure the queues and deliver. I would simply defer all weekend as I have done for years, but this time around my need came too quick to implement more orthodox methods and I need to interact with several recipients mail in the meantime. Thanks for all the help so far guys! jlc
