Why is My IP Address Blacklisted by UCEPROTECT?

Why is my IP address blacklisted by UCEPROTECT?

UCEPROTECT recently changed their listing policy and this caused IP addresses from the Contabo network to be listed in their so-called "Level 3" blacklist. Changes have been made to solve this issue immediately by Contabo. 

Can my IP address be de-blacklisted by Contabo? 

Contabo do not have any influence on the delisting process as such it is not possible to give an estimated time for the delisting at UCEPROTECT. Changes have been made to meet UCEPROTECT's updated policy which should hopefully help with your IP address being de-listed by UCEPROTECT.

What effects will my IP address being blacklisted by UCEPROTECT have?

Big mail providers (e.g. Gmail, Hotmail, Yahoo) are not using the UCEPROTECT filters at all and e-mails to those providers are therefore not affected by this listing.

Even smaller mail servers using the UCEPROTECT filters will most likely not include the Level 3 rules since UCEPROTECT themselves consider the Level 3 filter as too strict.

While Contabo are still working on a final solution regarding the UCEPROTECT listing, the blacklisting as such should not have any impact on regular mail delivery from your server. Even though mail servers with a too strict filter setup may be affected, the current listing can be considered uncritical for general mail delivery.
