A significant percentage of SMTP issues are related to authentication errors. To address this, review your SMTP server's authentication settings. Ensure correct username and password, and consider implementing advanced authentication techniques like SPF, DKIM, and DMARC where possible. 

Inspecting Email Content 

Sometimes, the problem isn't with SMTP settings but with email content. Examine the test report for details about the email body being flagged as spam or rejected. Revising your email structure, format, and content might be necessary to improve deliverability. 

Following Up With Regular Testing 

Optimizing your SMTP settings isn't a one-and-done affair. It requires regular reassessment as server status, email volume, cyber threats, and content preferences constantly change. Make it a habit to conduct regular SMTP tests to reevaluate and readjust your settings. 

By carefully analyzing your SMTP test results and adjusting your settings accordingly, you'll be on your way to maximizing your email delivery rates and ensuring your SMTP server performs at its best.
