Diagnostic-Code: smtp; 550 No RDNS entry for 194.xx.xxx.xx

2 years ago

Guten Tag,

ich bekomme diesen Hinweis, dass meine Nachrichten nicht zugestellt werden konnten:

Diagnostic-Code: smtp; 550 No RDNS entry for 194.xx.xxx.xx

Ich habe schon vielfach Mails an den Empfänger geschickt, derzeit ist es aber nicht möglich. Woran liegt das?
