    Grüße,

    ich stehe vor einem Problem, ich kann plötzlich keine E-Mails mehr versenden über meinen Externen Mailserver. Jedesmal wenn ich versuche mich zu verbinden mit Outlook erhalte ich einen Socketfehler 10060. Ich habe dann natürlich mal geschaut ob auf den Ports gelauscht wird

    netstat -tanp | grep :25
    Dann in den Mail Logs geschaut, das einzige was ich bekomme ist das hier dazu:
    Code:

    service postfix status
    Die Error Log sagen
    Wobei Pong mein Master Server ist. Hier habe ich zumindest eine neuerstellung des Fully qualified domain name in die Wege geleitet.

    Was mich besonders daran verwundert ist das da steht er hat 0 Sekunden gewartet. Ich habe auch keinen indiz was da plötzlich los ist und warum nix mehr geht, vor einigen Tagen noch war alles kein Problem. Reboot habe ich z.B. auch mal gemacht.

    Ah problem gefunden, ich habe auf LTE umgestellt und die Telekom kam auf die GENIALE idee nur externe Mailserver zulassen die gewhitelistet sind. Wtf,- wer macht denn sowas dummes. *wirft mit Torten*

    Da muss man erstmal drauf kommen :p, ich habe meinen halben Server auseinander genommen um das Problem zu finden ^_^. Also Dumm ist relativ, ich rege mich halt darüber auf das sowas nicht ordentlich propagandiert wird. Für Geschäftliche dinge ist das echt nervig wenn man es nicht weiß. Dachte schon mein Mailserver hat was an der Mütze vor allem weil ich über meine anderen konten alles reibungslos versenden konnte.
