Looks like sendmail is unable to resolve its own domain name to an IP address.

The fix is to make sure there are DNS records for all your (externally visible?) IPs for your domains. In some cases your ISP can do this for you so you don't have to run a DNS server.

BUT it sounds like you are using a consumer cable modem for this so its highly likely that you can't do this. Many cable modems use DHCP that renew their IP addresses everyday - your external IP might change. A possible fix for that is to maybe use a dynamic DNS system but you will have to keep it updated yourself...

In other words, this is a non-ideal setup to run a mail server off of. Maybe your ISP can give you a static IP?
