No :-( Well, there are ways to run external programs at
router's process function. See cf/process.cf.
Observe how e.g. 'core*' files are treated.
There you could run a program that mutates the file, and
then let normal processing continue. Something like:
That mutator can create temporary files which
have their name leading with DOTS:
(in zmsh script..)
When things are complete, the mutator shall overwrite
the original message file with new content.
(spool-file name should begin with i-node number of
the file even after it has been mutated..)
