Hey Stefan,

we hadn't any problems with them. We wrote them about our block on 14.01. and 
they did respond on the same day.
When did you wrote them ? Did your wrote postmas...@ewetel.net or did you wrote 
postmas...@ewe.net ?

Based on their answer, i think they have a internal list with dynamic ip ranges.

Best,
Jan-Philipp

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.

Hi Stefan,

This could also happen because your PTR record of sending IP address resolves 
with 3 IPs e:
IP  116.203.31.6 - PTR securetransport.cubewerk.de - IPs 178.254.23.77; 
116.203.31.6; 188.68.39.254

I know that technically it is nothing bad but, I can imagine why some sensors 
could return errors, especially since the 3 IP addresses are from different 
ASNs:


I guess those 3 IPs are set as fallback in this situation?

Looks like there is at least one RBL around, that list our IP as dynamic.

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  
gives a /16 belonging to our old friends Hetzner.
