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.
