I am trying to deal with the mediaone==>attbi mess. My setup is a firewall (horne.ne.mediaone.net) that forwards all mail to a "smart host" behind the firewall. In three attempts (email, phone) I have not encountered anyone at attbi who can say whether xxx.ne.mediaone.net will ==> xxx.attbi.net. I am assuming not. I went to dyndns.org (thanks) and set up a new hostname, horne.homelinux.net, pointing at my (mostly static) IP. Things seemed to work, to first order. To get email working I did the following hack - in sendmail.cf on the firewall, I added a hostname so -- Cwlocalhost horne.homelinux.net (entire domain is masqueraded) Now mail to eg steve at horne.homelinux.net gets to me. To fix outgoing mail to have the correct domain, I changed sendmail.cf on the smart host as follows: DMhorne.ne.mediaone.net to DMhorne.homelinux.net A couple quick tests seemed to do the right thing. Is this sufficient, or is there more to do? It surprised me that I didn't have to change the "domain" line in resolv.conf -- it kept being overwritten by the dhcp script so I left it alone. I don't run a web server - just family email and ssh. Thanks, Steve
