At the moment I block files with certain extensions, mostly exe and
double extensionsins.
Theese emails can later on be inspected and submitted to various
services for inspections thanks to the extraction and saving of banned
files.
But what if I want to save the email that I find suspicious for later
inspection(i.e .js) without rejecting the email.
As far as I know I cannot tell postfix to save an extra copy of an email
if it contains .js files.
The whole reason for this adventure is that antiviruses don't catch that
much anymore and the suspicious files has to be sent to a sandbox which
might take ten minutes to answer and then it cannot be inline.
