Per the RFC, Hostnames must begin with a letter (a-zA-Z), they can not begin with a number. Because of some issues we've ran into with exim recently, we've started to enforce this rule in order to be compliant with the RFC. If your servers hostname begins with a number, you will receive licensing errors and will not be able to license the server again until you resolve the hostname issues.
