What the documentation says6Technical articles
Documentation from Spamhaus explains that Maintaining a clean IP reputation is essential. Mimecast and Proofpoint both utilize real-time blacklists (RBLs) like Spamhaus to identify and block spammers. Ensure your IP address is not listed on any major RBLs.
Documentation from DKIM.org explains how to implement DKIM (DomainKeys Identified Mail) to digitally sign your emails. This cryptographic signature verifies that the email was sent by an authorized sender and has not been tampered with, enhancing your credibility with Mimecast and Proofpoint.
Documentation from Proofpoint Support outlines that Proofpoint emphasizes the importance of sender authentication protocols like SPF, DKIM, and DMARC. Properly implementing these protocols can significantly improve inbox placement by verifying the sender's identity.
Documentation from Mimecast Documentation explains that Mimecast uses a variety of reputation checks, including IP reputation, domain reputation, and sender reputation, to identify and block malicious email. Senders with poor reputation scores are more likely to have their email filtered into quarantine or blocked.
Documentation from RFC outlines the technical specification for SPF (Sender Policy Framework) records, which are crucial for email authentication and preventing spoofing. Properly configuring SPF records ensures that only authorized mail servers can send emails on behalf of your domain, improving your sender reputation with Mimecast and Proofpoint.
Documentation from DMARC.org explains Implementing DMARC (Domain-based Message Authentication, Reporting & Conformance) allows you to specify how email receivers should handle emails that fail SPF and DKIM checks. A strong DMARC policy (e.g., p=reject) can significantly improve your domain's reputation with Mimecast and Proofpoint.
