We are currently aware of an issue where the logs in the SMX email admin portal are not displaying at present. Mail flow is not impacted . We are investigating this issue at present and we will update you once we have further information.
This issue has now been resolved , thank you for your patience.
Adjustment to the Quarantine Self-Release notification emails: You may notice that the SMX logo has been removed from the top of the quarantine self release emails . We found that the logo was not rendering correctly for users on Microsoft Outlook, causing display issues. To ensure the email remains clean, readable, and consistent across all platforms and devices, we have decided to remove the SMX logo from the top of all QSR emails. All links and functionality within the email remain exactly the same.
