Orange postmaster

Market share and history of ISP

Historically named Wanadoo at its creation in 1995 by France Telecom, this ISP changed its name for the Orange brand in 2006. Since then, this ISP regroups wanadoo.fr and orange.fr domains in one and unique webmail. Also, since 2007, Orange only provides orange.fr e-mail addresses.

With more than 40% market share, Orange is the biggest French ISP. Its webmail is also one of the most used in France, just behind those of hotmail/outlook.com and gmail.com.

Anti-Spam Measures

To protect its messaging infrastructure, Orange relies on the Cloudmark Antispam Solution. Orange also uses solutions provided by Vade (ex-Vade Secure) for dynamic spam filtering.

Feedback Loop

Orange has partnered with Signal Spam to provide a feedback loop to senders who are members of the Signal Spam Association, under some conditions. There are two different Complaint Feedback Loops for Orange : an Aggregated Complaint Feedback Loop, similar to Gmail’s one, and an ARF Complaint Feedback Loop.

How does the Aggregated Complaint Feedback Loop work at Orange and how can we access it?
The aggregated Complaint Feedback Loop is a CSV file format containing Complaint volumes per IP and per day. This aggregated Complaint Feedback Loop is accessible to Signal Spam members.

How does the ARF Complaint Feedback Loop work at Orangeand how can we access it?
The ARF Complaint Feedback Loop consists of unit reports in ARF format, sent to a dedicated email address. This ARF Complaint Feedback Loop only contains complaints from Orange Mail service users who have consented to share this information with third parties. This ARF Complaint Feedback Loop is accessible to some Signal Spam members, upon validation by Orange Abuse Desk.

Postmastery's customers can track Orange complaint rates in the Reputation Monitor module of the Postmastery Console as well as tracking reputation and complaint data for IP addresses and domains from the world's leading anti-spam solutions including Spamhaus, Cloudmark, Abusix, SURBL, SORBs and Trend Micro.
