It is. Remove all traces of 'dns' from the hosts entry in the service.switch file if you don't want DNS lookups. You also need to have a FQDN for your host in /etc/hosts. > > It is not normal that the modem connects if there is no mail to send. Sendmail wants to know the FQDN of the host it's running on. If it can't find it elsewhere, it tries DNS. It does this on Linux too. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
