I just physically moved a mailserver across the street to a new office, and also moved it onto a different ISP. I changed /etc/resolv.conf to the new ISP's dns servers. Suddenly I can't receive any mail from anybody. sendmail[3380]: n2V6Sw4k003380: ruleset=check_m ail, arg1=<ltsp-discuss-bounces@xxxxxxxxxxxxxxxxxxxxx>, relay=[142.165.72.21], r eject=451 4.1.8 Domain of sender address ltsp-discuss-bounces@xxxxxxxxxxxxxxxxxx net does not resolve And so on. Everything is rejected with a 451 4.1.8. I uncommented "dnl FEATURE(`accept_unresolvable_domains')dnl" in sendmail.mc, and now I can receive mail again. I can dig any mx record from that server without any problem and I can send email out to anyone without problem too. So what did I not change? It worked fine before as it was, and as I said, all I did was move the machine across the street, give it a new IP address and edit /etc/resolv.conf. In fact, I didn't even give the actual machine a new address. It lives behind a router and all I had to do was give the router the new WAN address. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
