Your router should have a status page (I know there's one on my netgear and linksys routers) that shows the ip address and dns servers that were assigned via dhcp. But your local router at 192.168.1.1, being in the /etc/resolv.conf file, must be acting as a caching dns proxy which means that it would internally have it's own resolv.conf file updated with those values from the ISP. So the fact that the bounces are occurring because of dns seems odd. Are you sure it's actually a dns issue? My mail server is configured to connect to my isp to relay outgoing mail (some folks will block email if it originates from a non-static entity); if, for example, you were configured to upload to mail.cableone.net (or whatever), it might be there where the failure is occurring. What you really need to do is dig into your syslog and see what the error is that your mailer is reporting; that's going to indicate what you need to do to resolve it. -- [email protected] mailing list
