I have installed Hexamail on LINUX but cannot connect to it with the remote admin. How can I fix this?
Hexamail products use TCP/IP ports 23000-23030 for communication between the service and the admin. Be sure that those ports are available, and that any secure-Linux products (SELinux, AppArmor, RSBAC, grsecurity) have been configured such that they will allow the Hexamail processes access to these ports. Once you are sure Hexamail has access to the correct ports, be sure to folow the Remote Administration setup instructions
