What the documentation says5Technical articles
Documentation from Microsoft explains that monitoring IP reputation through tools like Sender Reputation Data (SRD) is crucial for identifying potential issues. SRD provides insights into the sending volume, spam complaints, and other metrics associated with your IP address, enabling you to take proactive measures to address any negative trends. Unusual IP activity can indicate a compromise, or someone is using a DNS record incorrectly.

Documentation from SparkPost explains that implementing SPF, DKIM, and DMARC for sender authentication is a crucial step to safeguard your IP reputation. These protocols help verify that emails are sent from authorized sources and protect against domain spoofing and phishing attacks. SparkPost advises that you should regularly review and update authentication settings to prevent malicious actors from exploiting vulnerabilities in your email infrastructure. They also recommend limiting the amount of includes in your SPF record to avoid DNS lookup errors.
Documentation from DMARC.org explains that DMARC, which builds on SPF and DKIM, helps email receivers decide what to do with emails that fail authentication checks. This can prevent attackers from spoofing your domain. Implement and monitor DMARC records to gain visibility into your email authentication ecosystem, identify potential spoofing attempts, and protect your brand's reputation.
Documentation from RFC-Editor explains that SPF records authorize mail servers to send emails on behalf of a domain, preventing spammers from forging the 'From' address.
