Dieser Beitrag ist nun extra da ich mich auf ein Detail nach dem anderen konzentriere.
Ich kann zwar per telnet eine Verbindung zu Port 25 herstellen, aber fast egal was ich dann eingebe, die Verbindung wird dann abgebaut.
Also schon das hier scheitert:
Code: Alles auswählen
telnet eins.xxx.tld 25
Trying 178.63.xx.xx...
Connected to eins.xxx.tld.
Escape character is '^]'.
EHLO eins.xxx.tld
Connection closed by foreign host.
Code: Alles auswählen
