Exchange Online Rules (Reject but allow message to be delivered)
I was able to set up an Exchange Online Rule that will allow the message flow to recipient with an appended Subject [*Vulgarity*]. Within the same rule I added a BCC to a mailbox. The Mailbox was created with auto-reply can response, allowing the user to receive the email and send a reply to the sender.
It all worked great excepts my list of Bad Words. The list contain words commonly used like "balls" creating a lot of false positive, will need to fine tune the list.
You can't, since you have selected to reject the message any subsequent actions such as changing the subject will be ignored.
