Hi. I'm working in a new SPF check utility to integrate our public lists at SPFBL.net and to improve the SPF response too:
github.com
This utility is like spfquery utility, but have two other return codes for special situations. Could anyone help me create a cPanel plugin for it?
SPFBL/client/spfbl.pl at master · leonamp/SPFBL
