We've installed TRAC version 1.4.3: [image: TRAC_version_info.png] Installed plugins: [image: Installed_plugins.png]
After some more testing and debugging, it appears the 'ticket_notify_email.txt' template was not correct. I've now used the template as can be found here <https://trac.edgewall.org/wiki/TracNotification>. Now it works for tickets reported by "normal" users. When a ticket is reported by "admin", the notification email is still not send (with error "*Failure sending notification on change to ticket #xx: AttributeError: 'list' object has no attribute 'update'"* This is no problem in normal usage as normally the admin account won't report tickets.
