Hi,
I have a setup, where emails received by mail server(postfix) are taken on and
the resulting email's body(html or plain text) and attachments are parsed to

I was wondering if the following scenario is feasible with Postfix. I

The first solution is amavis. But if you don't want to install amavis, there's
another trick using shell scripts
Save the script below to some file which is accessible in your $PATH for my
