Hi Craig,
We found some unexpected behaviour in the seminar event-notifications, running on 10.2.
We noticed that the 'reply to' address was filled with the name of an event-manager. This manager was even suspended in Totara.
Since we don't want to allow large audiences to reply on notifications to one individual business mail address this caused an issue.
During tests we found that Totara picks the first eventmanager from the top of the list, sorted alphabetically on family name.
As a workaround we created an extra account 'Administrator', which shows on top of the list.
Kind regards,
Gert-Jan.
