How It Works

SPF (Sender Policy Framework) records tell receiving mail servers which IP addresses and domains are authorized to send email on behalf of your domain.

Qualifiers: + (Pass), - (Fail), ~ (SoftFail), ? (Neutral)

Mechanisms: ip4, ip6 (specific IPs), include (delegate to another domain), a (domain A record), mx (domain MX record)

Limits: Max 10 DNS lookups. The record must be under 255 characters per string (multiple strings allowed). ip4/ip6 do not count as DNS lookups.
