Ok, figured it out. Read up more on the postfix architecture and
confirmed that it should work as the content_filter will run on the mail
once it has been received and before it is delivered via smtp to its
destination. The issue was that I am submitting on the submission port
587 and needed to add the content_filter there. In fact I don't need two
IP addresses for the smtp delivered mail :)
