Receivers don't block email from new IPs by default; they block them when they notice something amiss with the email (be it improper authentication, spam complaints, or something else). That looks like a too generalised assessment to me. As I mentioned in a different thread on this mailing list, my experience with Telekom / T-Online has been that their MXs soft-block servers with unfamiliar IPs from handing over email by default. There have been lengthy threads about this behavior of t-online.de like https://www.mail-archive.com/mailop@mailop.org/msg17245.html Actually this is even documented in their mail server policy: „A block may be in place, in particular, if you want to use an IP address that you have not previously used for sending e-mails“ https://postmaster.t-online.de/index.en.html#t4.7 Read: No throttling but a permanent block which can only be lifted by manual intervention. I strongly discourage such an approach for reasons already mentioned, however there are in fact postmasters who put servers without a reputation (new servers) in the same basket as spam sending servers. — 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.
