That can be done using a system filter, e.g.:

### Tag Subject line of recognized Spam Mails:
if "${if def:header_X-New-Subject: {there}}" is there
then
headers remove subject
headers add "Subject: $h_X-New-Subject:"
headers remove X-New-Subject
endif

...where the X-New-Subject: is created in an ACL.

Christian Schmidt
