Hi, I'm experiencing routing issues to freenet.de MX since almost 3 days.
I can't even lookup the domain as I cannot reach their NS, but the same happens even if I try to ping their email server IP address: 194.97.8.138 195.4.92.217 From my servers @OVH they are not reachable at all. I checked the IPs at https://check-host.net/check-ping and I see both IP pings from most places but a netherland one, hong kong and 4 russians sources (by comparison my own IPs are reachable from all of those sources). Failing traceroutes from check-host.net and from my IPs stuck at a Cloudflare IP: # traceroute 194.97.8.138 traceroute to 194.97.8.138 (194.97.8.138), 30 hops max, 60 byte packets 1 MYIP 0.373 ms 0.484 ms 0.590 ms 2 10.17.50.74 (10.17.50.74) 0.356 ms 10.17.50.72 (10.17.50.72) 0.396 ms 0.458 ms 3 10.73.17.68 (10.73.17.68) 0.101 ms 10.73.16.116 (10.73.16.116) 0.107 ms 10.73.17.70 (10.73.17.70) 0.134 ms 4 10.95.64.142 (10.95.64.142) 1.027 ms 10.95.64.156 (10.95.64.156) 0.424 ms 10.95.64.136 (10.95.64.136) 0.421 ms 5 par-gsw-sbb1-nc5.fr.eu (54.36.50.228) 3.949 ms 3.825 ms 3.821 ms 6 10.200.2.85 (10.200.2.85) 4.079 ms 10.200.2.77 (10.200.2.77) 71.136 ms 71.123 ms 7 * * * 8 172.71.120.4 (172.71.120.4) 4.689 ms 141.101.67.52 (141.101.67.52) 4.538 ms 4.578 ms 9 172.71.133.105 (172.71.133.105) 3.842 ms 172.71.129.237 (172.71.129.237) 4.226 ms 172.69.187.98 (172.69.187.98) 4.214 ms 10 172.71.133.23 (172.71.133.23) 5.352 ms 172.71.117.70 (172.71.117.70) 4.631 ms 172.71.121.67 (172.71.121.67) 4.512 ms 11 * * * 12 * * * 13 * * * I thought it was a peering issue, but 3 days should be enough for someone to detect and fix it. It doesn't look like a blacklisting issue as I cannot even query their authoritative NS and I can't do that even from IPs that never sent emails. I also checked OVH looking glass and they fail routing to freenet from all of their DCs: https://lg.ovh.net/traceroute/sgp+vin+sbg+bhs+hil+rbx+lim+bom+gra+waw+syd1+eri/ipv4?q=194.97.8.138 I also tried using OVH hosted email to write an email to a freenet.de domain and it resulted in a "Domain not found" error, so to confirm the whole OVH network can't reach the freenet.de NS. I opened a ticket to OVH but they closed it telling me the traceroute show the problem in outside their network (last working hop is a cloudflare IP). Peering/routing is not my field, so I'm looking for other people with problems sending emails to freenet.de and for suggestions on how/who to contact to fix the issue (maybe I should look for an NOC-op mailing list?) .
