sehh Posted December 24, 2017 Share Posted December 24, 2017 This might be off-topic but I would appreciate some help because I am at a loss I've got a server with Linode and it comes with two IP addresses, one IPv4 and one IPv6. The server is running CentOS 7, with Apache virtualhosts that host static html pages and postfix/dovecot for my personal email. So far so good. Now here comes the crazy thing. Spamhaus will list my IPv6 address in their SBLCSS blacklist, continuously (I delist and a few hours later its listed again). The server is not compromised, its a vanilla CentOS 7 with SELinux enabled and running Apache for static html pages, the server cpu usage is 0% and network is also at 0%. I even shutdown the server and my IPv6 address STILL got listed by Spamhaus even tough the server was turned off. I am can only conclude that my server is not compromised, maybe Spamhaus is running some kind of net-block-wide auto-block system that also covers my own IPv6 address. My IPv4 has never been listed, in case you are wondering, and neither of my two addresses got listed on any other blacklist that I know of. I tried to contact Spamhaus but they don't have any contact information on their website. I would appreciate any suggestions please. Link to comment Share on other sites More sharing options...
