Ok, the basics. I have a linux box server in my basement. Unfortuantly, since yesterday, I have moved 800 miles away. Yet, I have full shell access and can do just about anything that could be done on the prompt of the server. (ie. I am the system admin) Running RHLinux Psyche. The server is running Sendmail 10. I'm familar with the protocol and what it all means along with the basics of how MTA works. My problem is this, I can't figure out why, it's trying to send things from localhost.nycap.rr.com. It shouldn't even KNOW that dns as far as I know. The server should think it's domain is finn.ws and that nycap.rr.com is just a hop. Unless of course it's going out and trying to determine it's dns from the routers. . . I can't "allow" localhost.nycap.rr.com because that just simply doesn't exist (nycap.rr.com is the New York Capital Area Roadrunner domain) localhost would just not fit there. At this point what I really think my problem may be is that it's trying to send from that dns instead of my domain. . I have no idea why it would do this nor why other trials with languages like PHP would do the same. .
Furthermore. the mail server is functional. I DO send mail from inside my domain and outside with this server using client side applications like IE and Netscape on machines from on internal networks to Chili. . .
I hope that clears up any ambiguity with my previous messages. I didn't add any code here as I've gotten the same results with PHP, Perl and am not getting any errors on that side. The only place I find errors is in my maillog files. (I don't even have any mail sitting in que). The maillog errors are c/p'd above.
Thanks for all your advice so far. I have found things that were wrong from your advice unforunatly they had nothing to do with this problem.
I'm frightened by what I see, but somehow I know that there is much more to come.
