This is an advanced SPF check tool that integrates the SPFBL.net public lists and other validations. It's like spfquery tool, but have three other return codes for special situations. This utility replaces SPF and RBL verifications in the same time.

Your cPanel must have "move to Junk folder" implementation that uses "X-Spam-Flag: YES" header, like Spamassasin does.
