whitelisting
The Certified Senders Alliance (CSA) provides a whitelist, reputation data and training related to email marketing best practices. It is a service of the Europe-based internet industry association eco. As the CSA describes themselves, “[they act] as a neutral interface between mailbox providers and senders of commercial emails.” Internet company (mailbox provider, web portal and search engine) Seznam has joined the CSA and has implemented the CSA “certified IP list.” Seznam operates the largest Czech freemail service, Email.cz, which is actively used by more than six million users every month.

The head of Orange’s Anti-Abuse and Internet Security team has been kind enough to let the Mailop team know that in a few weeks, they will be bringing new IP ranges live, to send mail. Mail from Orange FR subscribers will be coming from any of these IP address ranges: 80.12.242.0/25, 80.12.242.128/29, 193.252.23.210/31, 193.252.23.212/30, 193.252.23.66, 193.252.22.0/25, 193.252.22.210/31, 193.252.22.212/30ISPs, mailbox providers and anti-spam filterers who wish to whitelist/allow list mail from legitimate ISPs may want to update their filters to allow through mail from these IP ranges.
