Nerds Mail Protection Ensures Mail Continuity. When your mail servers (or your hosting company’s mail servers) are not available – you cannot receive or send time-critical email messages.  Nerds Mail Protection changes that.  If your mail cannot be delivered, we will hold it for you (for up to four days).  Most email filtering services will do that.  We go one step further.  While the mail is being held, you can access it through our web dashboard.  You can view new messages, respond to them, and even create new ones.  When your normal mail servers “come back online”, the mail we have been holding for you will be delivered.
