spf_parse

Code Climate Build Status Test Coverage

The spf_parse library searches the spf records for a host. We assume the host uses standard spf 'selectors', and also check if they use their own 'selector'.

Examples

CLI

-use a single domain

spf google.com
____________________________
SPF record search for google.com
  - found SPF record for google.com at google.com:
  v=spf1 include:_spf.google.com ip4:216.73.93.70/31 ip4:216.73.93.72/31 ~all
____________________________

-or a bunch in a row

spf trailofbits.com facebook.com yahoo.com
____________________________
SPF record search for trailofbits.com
  - found SPF record for trailofbits.com at trailofbits.com:
  v=spf1 include:_spf.google.com ~all
____________________________

____________________________
SPF record search for facebook.com
  - found SPF record for facebook.com at facebook.com:
  v=spf1 redirect=_spf.facebook.com
____________________________

____________________________
SPF record search for yahoo.com
  - found SPF record for yahoo.com at yahoo.com:
