Enabled by default and allows anonymous (not logged in) users to send packages to registered application users or domains.
If enabled, it is possible since version 2.3.10 to use a special URL with built in parameters, that modifies the anonymous sending form, like setting a fixed recipient. Such a link can be than used to direct anonymous users to send a package to a specific recipient. For example in this way: https://sofie.sonpo.cz/#/?template&recipient=sofie@sonpo.cz&password=false&expiration=false .
If disabled, it is so called “request only” mode, which means anonymous users cannot send packages by themselves and can only react to a request sent by a registered user. Also sets and fixes the welcome page content to the Login state (ignoring settings in Settings - Configuration - Appearance).

A comma separated list of IP addresses and ranges (in CIDR notation), which define the closed (protected, secure) environment. According to these all sent packages are classified and assigned a "source", either in the closed environment or outside it (in an open environment). Similarly, when a user is accessing a package, a "target" is evaluated, based on the IP address from which the user is accessing the package. Whether the user's access to the package is allowed, is determined by the pair "source" → "target" and the settings below.
If any addresses or ranges for the closed environment are set, all users of the application will see a lock icon on the right side of the top bar. The icon will either be an unlocked or locked lock, representing whether the environment the user is currently in is open or closed.
