Federation filter

Kitsune has a basic federation filter. It has two main modes of operation:

• Allowlist-based
• Denylist-based

The domain list supports globbing, so can, among other things, define wildcard blocks.

Allowlist

As the name might suggests, this mode allows instance administrators to define a set list of domains the server is allowed to interact with.
Federation attempts from any other server are rejected.

Configuration example

[instance.federation-filter]
type = "allow" 
domains = ["*.myfriends.com", "cool-instan.ce"]

Denylist

This is the opposite of the allowlist-based federation. In this mode, Kitsune generally accepts federation attempts from any instance except the ones defined in the domain list.

Configuration example

[instance.federation-filter]
type = "deny"
domains = ["*.badstuff.com", "mean-people.biz"]
