I had assumed they would set it the way they + wanted; and indeed my experiments on Linux seem to show that in some + cases they do (I could influence IPv6 lookups but not IPv4 lookups). + To be on the safe side, however, I have now made the interface to + host_find_byname() similar to host_find_bydns(), with an argument + containing the DNS resolver options. The host_find_byname() function now + sets these options at its start, just as host_find_bydns() does. The smtp + transport options dns_qualify_single and dns_search_parents are passed to + host_find_byname() when gethostbyname=TRUE in this transport. Other uses + of host_find_byname() use the default settings of RES_DEFNAMES + (qualify_single) but not RES_DNSRCH (search_parents). + Exim version 4.63 ----------------- |
