Postfix works well enough with libresolv, and supports many older platforms. Moving to libunbound, which is not as widely deployed is not worth the benefit. The base libresolv library should be enhanced to at least catch up with BSD-like systems and offer res_ninit(), res_nsearch(), ... Beyond that it would be good to be able to tell libresolv: * I want AD without RRSIG and to ask libresolv: - Do you trust the AD bit from your nameservers? with that and an appropriate administrator-settable predicate in resolv.conf we're largely set. Applications which call res_setservers() should automatically receive AD=1. -- Viktor.
