Use SQL to seperate the domains into categories for each type? ie split
your mysql_localbox into mysql_forward_mx etc and then use the
"domains=" line with an SQL query to target the right router.
To avoid mail loops, add a header flag with a hashed value to can re-do
later and check for that.
eg
LOOKUP_FWDDOMAIN=SELECT domainname FROM client_domains WHERE domainname
= '${mysql_quote:$domain}' AND dtype = 'forward'
forwardomains:
driver = manualroute
domains = ${lookup mysql{LOOKUP_FWDDOMAIN}{$value}}
local_parts = ${lookup mysql{LOOKUP_ALL_USERS}{$value}}
route_data = ${lookup mysql{LOOKUP_ROUTEDATA}{$value}}
transport = remote_smtp
