Got a sudden surge in reported spam. Turns out every bit of it is coming from Colo Crossing IP blocks. No abuse web interfaces or open relays either, this is pure source spam with the same spams arriving from multiple IP blocks within Colo Crossing.
Turns out mail review shows we’ve last seen HAM from their IP blocks over 3 years ago. Seems like they’ve turned a corner. 192.227.128.0/17 198.23.128.0/17 172.245.0.0/16 -- Jo Rhett Net Consonance : net philanthropy to improve open source and internet projects.
