I don't believe there is an automated process. Our MTAs got blocked as well and they share the same apex domain as our website which includes an imprint. The whois information of the IP addresses include contact information as well and everything else t-online.de might ask for. Yet they still got blocked from the very first message on. It looks more like t-online.de blocks incoming connections from the whole world, except from a list of IP addresses they maintain internally. To get added to this list you have to a) contact them manually and b) fulfill arbitrary rules that t-online.de set up. If only 10% of all ESPs in the world would act like this and require manual requests so that one MTA can talk to another MTA, email would be unusable. -- 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.
