MTA-STS
not published
iCloud signs DKIM with Apple's domain, not yours. This means DKIM authenticates but never aligns for DMARC.
FIX
For better deliverability move to a provider that supports DKIM on customer domains (Google Workspace, Microsoft 365, Fastmail, etc.).
Your SPF record has no "all" mechanism and uses a "redirect=" modifier, which hands the whole policy to another domain. This is valid, but your protection is only as strong as the target record — make sure it ends in -all.
FIX
Verify the redirect target publishes a strict SPF policy (ending in -all). Do not add an "all" mechanism to this record: it would make the redirect be ignored.
MTA-STS protects against downgrade attacks during SMTP delivery. Recommended for serious senders.
FIX
Publish an MTA-STS policy at mta-sts.<your-domain> and a TXT record at _mta-sts.<your-domain>.
