Dear Dev Team,
I am one of user of Dreamhost and there is lot of issue regarding spam mail. Sometime mail generated from same domain with "subject : waiting for the Payment ". As per suggestion given by your team, we can restrict such mail using message filter option. But I have 50+ mail ID, it creates huge task for me to add filter for each mailbox. So you team shared me the community link for raising the new development for Message filtration for entire domain. I am requesting you to do such development.
