Post SMTP is designed with your website’s email deliverability and security in mind, offering advanced features like OAuth 2.0 authentication, detailed email logs, and instant failure alerts—all to help ensure your emails reach their destination safely and reliably.

Recently, a minor security oversight was identified through a security researcher participating in the Wordfence Bug Bounty program. This issue affects versions up to 3.6.1, where users with basic access rights could make unauthorized changes to email settings.

The great news is that the Post SMTP development team responded promptly by releasing updates that address this issue and strengthen access controls. This quick action shows our commitment to keeping the plugin secure and reliable for every user.

To maintain the highest level of protection and performance, it’s recommended to update your Post SMTP plugin to the latest version whenever updates are available. Staying up to date helps guard your website against vulnerabilities and ensures you benefit from the newest features and improvements.

In the end, we are grateful to Wordfence for helping us keep Post SMTP secure. We also thank our 400,000+ users for their continued support and trust.
