Habe einen Server bei 8Otrato hier der output:
mx0.serverkompetenz.de claims to be non-existent host
Code: Select all
WARNING: One or more of your mailservers is claiming to be a host other than what it really is (the SMTP greeting should be a 3-digit code, followed by a space or a dash, then the host name). If your mailserver sends out E-mail using this domain in its EHLO or HELO, your E-mail might get blocked by anti-spam software.
