I am trying to understand after-queue content filter feature to see if I
can run a filter to examine the mail classification. Reading the
'simple content filter example' it states 'deliver unfiltered mail to a
content filter with the postfix pipe. If I have the milter injecting
headers, are the headers available via content filter?
Yes, basically what I describe is using a second instance of
postfix as what that document calls an "advanced" content_filter.
