Try to send your email via web.de (browser), which might use servers with better reputation. See https://postmaster.web.de/en/email-server Mails classified as spam or external forwards seemingly take another route via mout-xforward.web.de. These servers are SBL-listed by intention, most likely because the spam probability is higher in this context. This separation helps mout.web.de to maintain a better reputation. Only web.de can tell why your email was routed that way. > $ dig -x 82.165.159.35 +short > mout-xforward.web.de. > > Can anyone from web.de help with this? The mail operators' list is better suited for this kind of question as an alternative to the contact form link provided by Viktor: https://www.mailop.org/ Best regards Gerald _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
