Hi,
I wanted to change the "Action Objects" "Modify Spam Subject" from "SPAM: __SUBJECT__" to "[EMAIL_SUSPECT!!!]: __SUBJECT__" and got the above error message,
I previously have done some comminication campaign on the header [EMAIL_SUSPECT!!!] to my users and wanted to preserve this header after changing from ScrollOut F1 to Proxmox Mail Gateway.
