mediumSPF uses ~all (softfail) instead of -all (hardfail)
Softfail still lets mailbox providers accept unauthorized senders. Upgrade to -all once you're confident all legitimate senders are covered.
→ Replace ~all with -all in your SPF record.
lowDMARC policy is quarantine, not reject
Quarantine sends unauthorized mail to spam. Reject blocks it outright. Move to reject once DMARC reports show no legitimate senders being affected.
→ Change p=quarantine to p=reject once you trust your reports.
lowOnly one MX host
Single MX means any outage or block at that host results in mail loss or bounces. Industry best practice is at least two MX records at different hosts.
→ Add a secondary MX at a different provider or a backup MX service.
