Sender Policy Framework
SPF identifies mail systems authorized to send for a domain.
What Chalo checks
Chalo resolves TXT records, finds v=spf1, and flags an explicit +all mechanism.
Passing signal
An SPF record exists and does not permit every sender.
Failing signal
No SPF record exists, or +all permits unauthorized senders.
How to fix it
Publish one SPF record covering legitimate senders. Validate includes before moving to a strict policy.
Example configuration
v=spf1 include:_spf.example.net -all
