That's something you should probably configure in your system for
configuring forwarding. If your system is just letting users create a
.forward file then it gets complicated. You can probably hack somthing
together in the routers, e.g. (based on the default configuration), add
the following to the userforward router:
address_data = forwarded=yes
and the following to the start of the routers:
check_forward:
driver = redirect
domains = ! +forward_ok_domains
condition = ${extract {forwarded}{$address_data} }
data = :fail: Address forwards to invalid domain
allow_fail
