ix.dnsbl.manitu.net
Help for mail server administrators
Stop any usage of ix.dnsbl.manitu.net IMMEDIATELY!
What you must do:
-
You MUST stop any queries to the dns zone
ix.dnsbl.manitu.net IMMEDIATELY (not tomorrow, not within a few days - NOW).
-
Do NOT wait until the issuer of your software (e.g. anti spam solution) has removed it from its defaults.
-
Do NOT wait until your operation system issuer have removed the dnsbl from any configuration.
-
Do NOT expect a full RFC compliant behaviour.
-
Do STOP abuse our dns servers. We are not a free service for your outdated configuration.
-
Do NOT write to us (manitu). We will not answer.
Why this is important:
-
Despite an RFC-compliant shutdown, we still receive millions of queries to our DNS servers. Too many administrators wrongly assume that UDP network traffic is free. It is NOT.
-
Our carriers / anti dDoS solution providers are starting to classify the usage of the no
longer existing dns zone
ix.dnsbl.manitu.net as ABUSE.
-
If you continue to use the blacklist your ipaddress any maybe your network (/24 or even more) or
even your whole AS will probably get blacklisted by the carriers / etc. we are using. This blacklisting may
not only affect traffic to us (manitu, AS34240) but also to other targets (this decision is up
to the carriers etc. themselves).
