Do I need to be connected to the Internet to use ZixMail?
Yes and no. When you are not connected to the Internet, you are unable to retrieve the necessary Public Keys and Certified Time-stamp needed to complete and send a ZixMail message. However, ZixMail provides a handy draft area which can safely store your ZixMail messages until you are connected to the Internet. Any previously received ZixMail messages can be read at any time.
