Good morning, I installed the new Yunohost 12.1.31 update and ended up on the spam list again. Until now everything had been quiet. When I run the diagnosis in Yunohost, I get this suggestion — do I have to do that?
Deine IP-Adresse oder Domäne 65........ ist auf der Blacklist auf Spamhaus ZEN
- It looks like the reason mentions ‘open resolver’.
This usually means your server is not using its local DNS, but a public, open, one.
Check the contents of/etc/resolv.conf, it should containnameserver 127.0.0.1.
Since this file is usually automatically generated, do not edit it manually. Check your DHCP settings, or your VPN settings if you are using one, or if you used a Debian image made by, for example, a VPS provider, look for acloudinitconfiguration.
You are most welcome on the YunoHost support channels to get help on this issue.
The verbatim blacklist reason is: “Error: open resolver; https://check.spamhaus.org/returnc/pub/2001:19f0:5000:1800:5400:5ff:fe01:2dc5/” - Nachdem Sie herausgefunden haben, weshalb Sie auf die Blacklist gesetzt wurden und dies behoben haben, zögern Sie nicht, nachzufragen, ob Ihre IP oder Ihre Domäne von ZEN Blocklist | Combined IP DNSBLs for effective email filtering entfernt werden kann
