Hi, for relative long time (some weeks) i have troubles with SORBS RBL. I do not use it at MTA nor rspamd level, but only in my script, which i run only manually when i need to inspect some IP status in depth, thus i cannot exceed any limits.
But queries to SORBS (concrete to safe.dnsbl.sorbs.net) are sometime
success (in mean no timeout), but mostly fails with timeout (message
from my script):
safe.dnsbl.sorbs.net: The DNS operation timed out after
5.105137348175049 seconds
I collect related NS records and try to ping them from another IP
(different ISP), to be sure that they are not blocked by me nor by my
ISP, and results corresponds with my experiences:
ns0.sorbs.net. 113.52.8.11 ping fail
ns2.sorbs.net. 87.106.246.125 ping fail
ns4.sorbs.net. 78.153.202.24 ping OK
ns5.sorbs.net. 72.12.198.241 ping fail
ns1175.dns.dyn.com. 108.59.166.201 ping fail
ns2174.dns.dyn.com. 108.59.168.201 ping fail
ns3179.dns.dyn.com. 108.59.170.201 ping fail
ns4151.dns.dyn.com. 108.59.172.201 ping fail
ns9.sorbs.net. 169.48.121.207 ping OK
rbldns10.sorbs.net. 185.87.186.55 ping OK
rbldns7.sorbs.net. 88.208.216.85 ping fail
rbldns0.sorbs.net. 113.52.8.50 ping fail
rbldns17.sorbs.net. 210.50.3.173 ping fail
rbldns3.sorbs.net. 74.208.146.124 ping fail
rbldns16.sorbs.net. 74.53.186.252 ping fail
rbldns8.sorbs.net. 89.150.195.2 ping fail
rbldns4.sorbs.net. 78.153.202.22 ping OK
rbldns15.sorbs.net. 87.106.246.154 ping fail
rbldns2.sorbs.net. 72.12.198.247 ping OK
rbldns18.sorbs.net. 72.12.198.248 ping OK
rbldns14.sorbs.net. 194.134.35.168 ping fail
rbldns12.sorbs.net. 74.208.146.124 ping fail
rbldns13.sorbs.net. 113.52.8.157 ping fail
rbldns6.sorbs.net. 194.134.35.204 ping fail
rbldns1.sorbs.net. 78.153.202.21 ping OK
rbldns11.sorbs.net. 216.12.212.155 ping fail
rbldns9.sorbs.net. 169.48.121.206 ping OK
As any can see, some responds, and some not...
I do not know, if they are not accessible or have ICMP blocked, but i
will expect, that if they block ICMP, they will block all not only some
hosts.
Please, encounter someone else this? Are here some problems on their
side?
thanks
