Mail bounces... "sender domain must exist"
This may not be technically
a pure Linux question, but since I'm running a Linux box and that's part of my problem, I figured I might as well ask it here.
I am connected to the Internet by a local cablemodem provider, MCHSI. I use a Dynamic DNS system, zeropain.com, to provide my machine with a domain name (terrania.zeropain.com); I send email from it using sendmail.
Lately, I've been getting some email bounces from some places I've tried to send mail. The error message follows, after LJ-cut, but the gist of the thing is they complain "sender domain must exist" and apparently they think terrania.zeropain.com doesn't.
Is there something I can do about this? (And if it involves setting sendmail or mutt to route my outgoing mail through my ISP's mail server instead, can you please tell me how to do that?)( Collapse ) Current Mood: annoyed
