Need PTR the same hostname email ?
I see some email sent to google require PTR the same hostname of email . So need create PTR the same hostname ?
example hostname 123smtp.test.com then PTR 12.12.12.12 123smtp.test.com ? or only need have PTR to primary domain as smtp01.test.com (anyname.test.com)
I check then see Microsoft using different with hostname
