Hi Victor, Why do you recommend so, now that Postfix strips RES_DEFNAMES from _res.options by default? This resolver bug aside :) (It used to work before the stripping, probably because I take care that localhost resolves either properly to 127.0.0.1/::1 or to NXDOMAIN in the domains I list in /etc/resolv.conf's "search" or "domain".) Best regards, Matthias
