The problem is that sendmail uses its own configuration file
(/etc/service.switch) and not NetBSD's own (/etc/resolv.conf).

If you create /etc/service.switch with just one line like

     hosts files bind

sendmail will consult /etc/hosts before the name service. This will enable
sendmail to send to local hosts when no internet connection is available.
You may have to install sendmail from NetBSD-current to get this to work.
