Yes, it is spam. > you got the email from a diff ip ? I am getting it via fetchmail from one of my mail servers, the one at sia.dkuug.dk > unknown domain is here sia.dkuug.dk Why is it not ezbck.ParteiTv.com ? fetchmail reports: "onfnp...@ezbck.parteitv.com>: Sender address rejected: Domain not found" > so > dig sia.dkuug.d A > or > dig sia.dkuug.dk MX > > it exists ? Yes, the A record exists (in the .dk domain, you missed the "k" there), but MX sia.dkuug.dk does not exist. Should it?

Hmm, I think postfix on my system uses the nameservers as recorded in /etc/resolv.conf?
