It has to. Milter modifications are made after the entire message
is received in a queue file. Adding headers in the middle of a file
would have a major performance impact.
I do not provide support for non-Postfix programs that depend on
the Postfix queue file structure. Those supported dependencies
will result in pure hell when I need to add functionality.
There is a Perl-based parser in Victor's qshape script which is
distributed with Postfix. This code will follow the Postfix pointer
records as needed, so if you just walk the file, you will eventually
find the X-MS-Floodstopper header if it is present.
You could also look at the file with "postcat -h" which is fully
supported.
Adding "postcat -e" support, using the same file editing primitives
as Milters, is a larger project.
