It might be better if you could show us your configuration.

I haven't used any of this personally, but that doesn't match my
reading of the documentation:

Based on my reading of the documentation linked above, try putting
quotes around "add" and "remove" ?

With something like this it's much more likely to be the user's
misunderstanding than to be a fault in the software.  It is however a
little unfortunate that the rendering of the documentation on the
rspamd Website leaves much to be desired from the formatting POV.

Incidentally you should _append_ any header like X-ENTRY so I think you
would want {-1, "VALUE"} instead of {0, "VALUE"} in the 'mods' table.
In general I'd be cautious about removing headers.
