It has already been mentioned in the discussion last month but to reiterate: You can send emails from random.subdomain.scconsult.com to Yahoo just fine as long as scconsult.com has a SOA record, which is and has always been mandatory anyway. IMHO this requirement by Yahoo is a non-issue and automatically met by everyone except three groups: 1. Domains with misconfigured DNS as seen in this thread. 2. DNS zones that span over multiple different organizational domains as seen in the thread last month. Domains under different administrative control must not share the same SOA record. 3. Emails from made-up domain names, ie from spammers or other miscreants. — BR Oliver ________________________________ dmTECH GmbH Am dm-Platz 1, 76227 Karlsruhe * Postfach 10 02 34, 76232 Karlsruhe Telefon 0721 5592-2500 Telefax 0721 5592-2777 dmt...@dm.de<mailto:dmt...@dm.de> * www.dmTECH.de<http://www.dmtech.de> GmbH: Sitz Karlsruhe, Registergericht Mannheim, HRB 104927 Geschäftsführer: Christoph Werner, Martin Dallmeier, Roman Melcher ________________________________ Datenschutzrechtliche Informationen Wenn Sie mit uns in Kontakt treten, beispielsweise wenn Sie an unser ServiceCenter Fragen haben, bei uns einkaufen oder unser dialogicum in Karlsruhe besuchen, mit uns in einer geschäftlichen Verbindung stehen oder sich bei uns bewerben, verarbeiten wir personenbezogene Daten.
