As you can see here (https://www.spamhaus.org/pbl/query/PBL1669837) the range 188.8.131.52/24 is listed on the Policy Block List (PBL) by Spamhaus which is meant to indicate that this range belongs to end-user/dial-up/cable/etc customers and is probably not meant to send emails.
However that range most definitely belongs to Digital Ocean (in fact the whole 184.108.40.206/16 does - see http://whois.domaintools.com/220.127.116.11) and has proper reverse DNS set up (as do all hosts in DO).
Does anyone have any technical contacts at Spamhaus? I guess this listing is due to some technical issue on their end, however I can’t get in touch with them (they are notoriously hard to get in touch with) and the only option I see on their site is to “remove one IP” - but I would like to tell them that the entire range is erroneously listed.
