Hi-ho. Posted about this a week or two ago, applied the suggested fix, but no difference. I'm trying to set up my home network so that we can send outgoing mail. The SMTP machine runs the Courier mail package. It has the hostname "gaea" and is a member of the domain "sysvi.com", or at least I think it should be, but whenever I try to relay mail out I get log messages like this: Nov 11 11:40:27 gaea courierd: newmsg,id=00006844.3A0D848B.00001569 Nov 11 11:40:27 gaea courierd: started,id=00006844.3A0D848B.00001569,from=<>,module=esmtp,host=gaea,addr=<mjinks@gaea> Nov 11 11:40:27 gaea courierd: Waiting. shutdown time=none, wakeup time=none, queuedelivering=2, inprogress=2 Nov 11 11:40:27 gaea courierd: completed,id=00006841.3A0D8486.00001564 Nov 11 11:40:27 gaea courierd: Waiting. shutdown time=none, wakeup time=none, queuedelivering=1, inprogress=1 Nov 11 11:40:27 gaea courieresmtp: id=00006844.3A0D848B.00001569,from=<>,addr=<mjinks@gaea>: configuration error: mail loops back to myself (MX problem). Nov 11 11:40:27 gaea courieresmtp: id=00006844.3A0D848B.00001569,from=<>,addr=<mjinks@gaea>,status: failure There is a registered FQDN for "gaea.sysvi.com" which points to my firewall. On my internal DNS, gaea.sysvi.com points to the real gaea. On gaea, /etc/defaultdomain reads "gaea.sysvi.com" currently, I've also tried this with the file reading "sysvi.com". /etc/HOSTNAME also reads "gaea.sysvi.com". The "hostname" entry in /etc/sysconfig/network is also "gaea.sysvi.com". But for some reason courier still thinks my mail is coming from "mjinks@gaea" rather than "[EMAIL PROTECTED]", and gets into trouble when it tries to send mail from a domain that doesn't exist. Any clues? -m _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
