Because dns.el directly uses /etc/resolv.conf. Wanderlust doesn't directly use /etc/resolv.conf. Wanderlust uses Emacs' open-network-stream. It may fail, because Emacs process caches /etc/resolv.conf by getaddrinfo/gethostbyname. A workaround is to install a DNS server locally for caching. Thanks, -- Tatsuya Kinoshita
