Autor: Todd Lubin Data: Para: exim-dev Asunto: [exim-dev] RES_DNSRCH resolver option when using manualroute router
When using a manualroute router specifying route_data with "byname", exim
calls [gethostbyname]. However, it explicitly disables the RES_DNSRCH
resolver option.
For dnslookup routers, there is a search_parents option, but for
manualroute routers it is permanently disabled.
It seems to me that this should either:
1. Be configurable within a manualroute router
2. Default to whatever the system-wide default is (which is often
enabled)
