Hello,
I can help you resolve the issue of emails from your company domain being rejected and ensure your email setup is secure and optimized. With over 5 years of experience in email security and domain configuration, I have successfully resolved similar issues for clients using Microsoft 365 and hosting providers like AEserver.com.
Approach to Resolve Your Issue:
Diagnosing the Rejection Issue:
Analyze email rejection messages to identify the cause, such as DNS misconfigurations, blacklisting, or SPF/DKIM/DMARC issues.
Fixing Domain Configuration:
Verify and correct SPF, DKIM, and DMARC records for your domain to ensure emails are authenticated and not flagged as spam.
Check your domain’s reputation and delist it if blacklisted.
Email Security Audit:
Conduct a security review to identify potential issues like compromised accounts or unauthorized use of your email domain.
Ensure all Microsoft 365 security settings (e.g., MFA, anti-phishing, and anti-spam policies) are correctly configured.
Testing and Validation:
Perform end-to-end tests to confirm emails are delivered successfully and securely.
