MX Records: MX Records (Mail Exchange Records) are a type of DNS record that are used to specify the mail servers for a domain. MX Records are used by email servers to route email messages to the correct mail server for a domain.
TXT Records: TXT Records (Text Records) are a type of DNS record that are used to store arbitrary text data in a DNS zone. TXT Records can be used for a variety of purposes, such as to store human-readable information about the domain, to store verification tokens for email authentication, or to store security information, such as SPF and DMARC records.
SPF: SPF (Sender Policy Framework) is a security mechanism that is used to prevent email spoofing. It works by publishing a list of authorized IP addresses or domain names that are allowed to send email on behalf of a domain in a DNS TXT record. When an email server receives a message from a domain, it can look up the SPF record for the domain and check whether the message originated from one of the authorized IP addresses or domains.
DMARC: DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a security mechanism that is used to prevent email spoofing and phishing. It works by publishing a policy in a DNS TXT record that specifies how email servers should handle messages that fail authentication checks, such as SPF or DKIM checks. DMARC allows domain owners to specify what actions should be taken when such messages are received, such as rejecting them or quarantining them in a spam folder.
DKIM: DKIM (DomainKeys Identified Mail) is a security mechanism that is used to authenticate email messages. It works by adding a digital signature to the headers of an email message, which can be used by email servers to verify that the message was actually sent by the domain that it claims to be from. This helps to prevent email spoofing and other types of email abuse.
Malware: Malware (malicious software) is any software that is designed to harm or exploit a computer system without the user’s knowledge or consent.
