Issues (4)
criticalDMARC record is invalid
Receivers ignore an invalid DMARC record, so no DMARC policy applies. Multiple DMARC records found (2). Only one is allowed.
→ Leave exactly one valid record at _dmarc.yourdomain.com, starting v=DMARC1 with a p= of none, quarantine or reject.
highMX IP 2800:3f0:4003:c14::1a has no PTR (reverse DNS)
Gmail and Microsoft both require reverse DNS on sending IPs. Without it, mail from this host is almost always rejected or spam-foldered.
→ Add a PTR record at your hosting provider. For cloud MTAs (AWS SES, Mailgun, etc.) this is managed by the provider.
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.
infoBlocklist status unknown for 3 MX IP(s)
2607:f8b0:4004:c1f::1b, 2a00:1450:400b:c02::1a, 2800:3f0:4003:c14::1a: no blocklist answered for these addresses (our queries failed, or the address is IPv6, which these IP blocklists don't cover). They are left out of the reputation score, neither clean nor listed.
