    I am currently at a branch because I am not getting any email from the server again, which can be seen again because of Corona that almost all email servers of companies are currently overloaded.

    Hi Speddy,

    it seems that your RDNS PTR is not valid.

    Your IP Address is 51.255.70.89, RDNS PTR is ns3613157.ip-51-255-70.eu


    What's your Hostname ?

    How do you present to the world in your EHLO command ?

    my hostname it ns3613157


    As I know, this should be in here


    Code
    1. ns3613157.ip-51-255-70.eu

    my hosts


    Code
    1. 127.0.0.1 ns3613157.ip-51-255-70.eu.local localhost
    2. 51.255.70.89 ns3613157.ip-51-255-70.eu ns3613157
    4. # The following lines are desirable for IPv6 capable hosts
    5. ::1 localhost ip6-localhost ip6-loopback
    6. fe00::0 ip6-localnet
    7. ff00::0 ip6-mcastprefix
    8. ff02::1 ip6-allnodes
    9. ff02::2 ip6-allrouters
    10. ff02::3 ip6-allhosts

    Sorry again for the late news, but I'm working in security and I'm at home right now.

    request a delisting:

    http://multirbl.valli.org/lookup/51.255.70.89.html


    afterwards request a delisting on gmx.net & web.de and provide them following link:

    https://mxtoolbox.com/SuperTool.aspx?action=smtp%3a51.255.70.89&run=toolpage

    What should I do with it it is only indicated that the ip is supposedly listed 3 times in a list no longer.

    You should probably change the PTR record to something more personal. You usually can't use the record your hosting company provides to you.
