Hi In 2013/2014 we also had to deal with a massive spam spike from orange.fr Our stats showed that the spam to ham ratio was at about 95% or higher from their 'mailserver' IP Range. After sending several emails to their different abuse and postmaster email addresses and trying to escalate the problem via orange.ch (now salt), as a last resort we blacklisted their whole IP Range via SWINOG Blacklist, which is used by many swiss ISP. This finally resulted in orange.fr getting in contact with us. Apparently the do receive and look at emails at their normal abuse contact address. But they never bother to reply, especially when they do not feel responsible for the specific IP addresses, even if they are in their range. The problem at that time was, that they had leased a part of their IP range to one of their branches in eastern europe and this branch had somehow been massively abused by spamers. After they were able to tell me which IP ranges belonged to their 'east europe' branch, we could shrink the blocked range to those specific ip addresses and this was also fine with their abuse desk, because they could clearly see the problem and more or less confirmed their colleagues in eastern europe apparently did not care so much about spam or being listed in anti-spam blacklists. Apparently this was not their problem. So, yes, try their abuse contact email address, write in french if somehow possible, and make clear you need a reply. Hopefully this will help.
