Wenn ich zuhause von meiner t-online IP Adresse zu meinem Server verbinde (SMTP), kann ich EMails problemlos (TLS, port 587) verschicken. Im Moment bin ich in einem anderen Bundesland unterwegs bei meiner Tochter und nutze deren Vodadingsbums-Anschluß.
Ich kann an meinen Server derzeit keine SMTP- Email absetzen. Der vodadingsbums-Client wird abgewiesen: Jul 18 21:01:00 myusername postfix/postscreen[4485]: CONNECT from [188.98.123.123]:50403 to [123.123.115.43]:25 Jul 18 21:01:00 myusername postfix/dnsblog[4489]: addr 188.98.123.123 listed by domain b.barracudacentral.org <http://b.barracudacentral.org/> as 127.0.0.2 Jul 18 21:01:00 myusername postfix/dnsblog[4490]: warning: dnsblog_query: lookup error for DNS query 123.123.98.188.list.dnswl.org <http://list.dnswl.org/>: Host or domain name not found.
