Club 1196053 - Spam eMails that don't have eMail address that can be blacklisted

Greetings! 


I am in Club 1196053 and we've recently gotten a few spam eMails that were formatted by the sender so that the eMail address isn't clear. The eMails are fowarded from FTH as expected with the option to Blackist the sender. When the blacklist link provided in the eMail (sample attached) is clicked the sender is not being added to the blacklist as the email address is invalid. Attached is an example of the result from clicking the link. When I receive an email that cannot be added to the blacklist with the link, I'm using the admin console to blacklist the reply to address.
 

Please provide the raw internet header so we can see what is going on.

Brian,

Thanks!

Buried in the raw header is 

They are probably using a hacked email account and trying to hide the email.

Block that email and hope they aren't too smart.
