I am not sure what you mean by "this stage of mail reception", or what
software you are using that may be limited in such a particular manner,
but generally speaking you are wrong.

For example: Postfix supports both before-queue filters and after-queue
filters. Milter-regex[1] supports both multi-header and body checks. The
milter protocol itself allows for both header and body manipulation.
