If I may make a suggestion:  rate-limit incoming connections from AWS, 
with a pinhole for Helpscout.  Spammers try only one if they are doing 
direct SMTP; legit mail servers will retry failed transmissions.

I used to do this with Postfix at the edge of a Web host network.

(Yes, yes, I know that compromised PHP scripts will inject mail into a 
real mail server, so rate-limiting only spreads out the pain.)
