You may have noticed that some of your inquiries from FlipKey have come in as "unrecognized email" over the past week or two. This is due to some changes FlipKey made in the message format. We released a patch to fix it last week. A change occurred again last night, so this morning we just released a patch that fixes it again. Please let us know if you continue seeing any issues with FlipKey inquiry emails or receive more "unrecognized email" alerts.
