Latest Tomcat 9 release, 9.0.115, contains fixes for all known issues in previous versions. Additionally, version 10.1.8 is quite old and you should consider upgrading to the latest 10.1.52. A 404 status usually indicates that the /files context isn’t mapped, or Tomcat can’t access the underlying path. Please check these on your current deployment: 1) Do you have webapps/files ? 2) Do you have conf/Catalina/localhost/files.xml? 3) Do you see any line indicating the error in Tomcat logs/ ? 4) Does your Windows account, under which the service is running, have read access to the attachments directory? Tomcat itself doesn’t send emails. The broken email notification may be directly related to the Jakarta namespace changes that come with Tomcat 10.1, which your app/libraries may not adhere to. We can investigate further if you provide the stack trace from the logs. Kind regards, Dimitris
