+      Whether you are trying to understand why a specific e-mail ended up in
+      SPAM/Junk for your daily Administrative duties or for your Red-Team
+      Phishing simulation purposes, this script is there for you to help!
+
+      This tool accepts on input an *.EML or *.txt file with all the SMTP
+      headers. It will then extract a subset of interesting headers and using
+      105+ tests will attempt to decode them as much as possible.
+
+      This script also extracts all IPv4 addresses and domain names and performs
+      full DNS resolution of them.
+
+      Resulting output will contain useful information on why this e-mail might
+      have been blocked.
