How to block spam that says its from IDnet

[john7]

My wife keeps getting spam (or worse as we haven't been so stupid to do anything with them) which say from IDnet. Support just say config er the spam filters to block it but have ignored my request as to how as it has IDnet in the sending address. So is I add IDnet to be blocked that isn't really going to help anything  from them. So any one any idea how to block tha last one IDNet via Docusign ?

I'm not sure if you're still with IDNet, John, but if so, if you log into the Customer Portal, scoll down to the Email settings, you'll find some configurable mail filters there.
