Hrm. It … works for us? Is this something that happens to work but is undocumented?

The router that uses that list, at least, seems to work as we intend:

manualmx:
driver = manualroute
domains = +manualmx_domains
transport = remote_smtp
route_data = ${lookup{$domain}lsearch{/etc/manualmx}}

Or am I misunderstanding?
