Hi, anyone around here from zxcs.nl or vimexx.nl? My customers complain that they can not sent emails to npsdriven.com or watersnip.nl. My recursor source addresses are 2607:f1c0:5c0:53::/64 2607:f1c0:5c1:53::/64 2001:8d8:5c0:453::/64 2001:8d8:5c1:453::/64 2001:ba0:5c0::/64 2a00:da00:5c0::/64 2a00:da00:5c0:3::/64 2a00:da00:5c0:4::/64 74.208.114.128/26 74.208.114.192/26 77.68.65.64/26 82.165.226.0/26 82.165.226.64/26 88.208.254.128/26 82.223.158.0/26 213.171.202.197/27 please remove firewall drop rules or low hashlimits (<50 qps) for the listed prefixes on your gear to allow your customers to communicate with my customers. I run the DNS for IONOS (incl. arsys, fasthosts, home.pl) 1&1, gmx.net, mail.com, web.de. (>100M email accounts) In case of any problems please contact abuse@ionos.com first. The emails sent there are read and reacted to. Cheers Thomas
