Checking SPF record...
SPF (Sender Policy Framework) is a TXT record that lists which servers are authorized to send mail for a domain. Receiving mail systems check the SPF record during delivery and may reject or quarantine mail from unlisted senders.

Remove unused include: chains or flatten them into ip4:/ip6: ranges; RFC 7208 §4.6.4 caps total DNS-resolving mechanisms at 10.

A missing or syntactically invalid record means receivers fall back to local heuristics — often unfavorable. Hard-fail (-all) gives the strongest guarantee but breaks legitimate forwarding; soft-fail (~all) is the common production compromise. If lookups approach the 10 limit, consolidate include: chains.
