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) -- ## List details at https://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
