Hi,
I find SpamCop reports very difficult to read.
I'm noting in recent reports these domains:
*.cloudflare.com (says it's one of the biggest networks)
.hubspotemail.net (LOOKs to be a free email marketer)
*.carbon60.net (says it's cloud services and solutions)
I can block domains with my ISP. I want to block these guys because they appear in most or all SPAMcop reports, but I don't want to interfere with SpamCop itself.
How can I go about finding out whether these companies are known to pass spam?
How also can I find out what to NOT block, so I don't upset SpamCop processes?
Thanks
