ممنون ولی من کار دقیق اونو می خواستم

A Sender Policy Framework (SPF) record indicates which mail servers are authorized to send mail for a domain. Email recipient servers perform a check: “Is this email coming from an authorized mail server?” If not, then the email in question is more likely to be spam. Your SPF DNS record lets the recipient server perform this verification. The SPF check verifies that an email comes from authorized servers.
A DomainKeys Identified Mail (DKIM) record adds a digital signature to emails your organization sends. Email recipient servers perform a check: “Does the signature match?” If so, then the email hasn’t been modified and is from a legitimate sender. Your DKIM DNS record lets the recipient server perform this verification. The DKIM check verifies that the message is signed and associated with the correct domain.
