keyway posted a topic in SpamCop Reporting HelpHi, I noticed that sendgrid.com is being devnulled. "( 188.8.131.52 ) To: firstname.lastname@example.org" Is there a method to determine why? I would like to know if escalating the spam report to their ISP would be appropriate. Looks like it's reaching me through their feed from "steadfast.net" http://abuse.net/lookup.phtml?domain=steadfast.net Thanks.
