Hi,
it's just DNS round robin for our senders. did not had a sigle issue with that over the previous 2 years. Still thinking, that ewetel/ewe just uses ancient RBLs, that reports the specific IP from a dynamic-block.

Looks like there is at least one RBL around, that list our IP as dynamic. https://www.rbl-dns.com/bl?ip=116.203.31.6 One just have to pay to get de-listed. What a wonderful world.

I am not surprised that Ewetel has guessed wrong: whois 116.203.31.6 -h whois.ripe.net <http://whois.ripe.net> gives a /16 belonging to our old friends Hetzner. -- Andrew C.
