This is a very simple and easy project for someone who knows what he is doing:
I need a Procmail Recipe to DECODE Base64-encoded email SUBJECT content, and to do a little filtering depending on the email subject content after the decoding on my email server.
I know how to do the filtering part, I only need the decoding part of the recipe. I only need the recipe, I will do all the testing.
More details very soon here: [url removed, login to view]
The email server runs under Debian 7.1 Wheezy.
