Saving the DKIM Selector works. Thanks. I probably should have been more thorough since I failed to mention that we need a way to export blacklists. whitelists and greylist exceptions to copy from one machine to the next.

I had a situation recently where my data center moved the instances to a new facility in the same area. My mistake was manually configuring the IP address rather than letting them handle it dynamically. I do use a separate /vmail partition that I never format. Once moved, it was impossible to communicate with it since it was a manual IP, and a new facility and address were assigned. I have the old databases still in /var/vmail, but have not been successful in restoring them. The ability to simply export these lists and save them locally would have easily prevented this. Moving the email from the old to the new folder has always been a piece of cake.
