Redmine

Redmine does not send reminders for closed issues.

In your case, the issue might not actually be considered closed by Redmine. Please check the status is really set as "Closed" in the Issue status page (Administration -> Issue statuses). If that flag is not set, Redmine will still treat the issue as open and include it in reminders.

If your Redmine is customized, that could also affect the behavior. Customizations include installed plugins, local patches, or changes to the core code.

In the standard code, the reminder task clearly filters only open issues. Because of that, a normal, unmodified Redmine should never send reminders for issues that are truly closed.

source:tags/6.0.7/app/models/mailer.rb#L615

    scope =
      Issue.open.where(
        "#{Issue.table_name}.assigned_to_id IS NOT NULL" \
          " AND #{Project.table_name}.status = #{Project::STATUS_ACTIVE}" \
          " AND #{Issue.table_name}.due_date <= ?", days.day.from_now.to_date
      )

Yes, I know, that's why I open this as a defect.

I've been using redmine for about 10 years now, so I know this is not a normal behavior. The issue is marked as closed ("fermé" in French), and this is the "closed" status that I have always been using :

It is not customized. I used to have one plugin, but I removed it some time ago during an upgrade.

I looked directly into the database I found something quite strange : issues.status_id = 8, which is NOT the id of "Fermé" fermé is id = 5 !
So there is a discrepancy between what I see on the issue page and what I see in the database.
I'll try to switch the issue to open and back to closed to see if this fixes the problem.

Another one, and this one is not even assigned to me ! I blurred the assignee for privacy, but it is not I !
Note that this is not a new reminder, I've been reminded for this task for some time but only realized it today :
