Allowed IP Addresses
This is the list of allowed IP4 or IPv6 addresses that can connect to your server for administration.
You can use CIDR notation, wildcards and ranges (e.g. 192.168.0.0/16, 192.*.*.*, 192.10-50.*.*, 0:0:0:0:0:0:0:*) or leave blank for any IP.
By setting this connections are restricted to ONLY those that match an entry in this list
The administrator password is used to ensure that only the authorized administrator of the Hexamail service can use the interface to configure Hexamail Server. Once you have applied a password change, you must also press the Connect or Switch Service and set the correct password for the connection, otherwise Hexamail Server Administration interface will no longer be able to connect to the service you are administrating. The password is typically only used for remote configuration.
