Apologies, this is actually expounding upon an existing Maileater processing idea.
People often reply back to a system generated email with an email containing embedded images. The only way to not lose this information is to configure the ‘Attach Entire Email’ option on the Mailbox. However doing this causes the system to generate two messages. The COMPLETELY useless, confusing, un-configurable and unpreventable “Updated via EMAIL interface.” Message which gets tagged in the Activity Log as the person who sent the reply (also ridiculous, this should be one of the system contacts if it has to be there at all) and then a supplemental email that contains the actual comment.
