I changed to this:
CHECKED Receive forum announcements and important notifications by email.
CHECKED Receive reply notification only for the first unread reply.
NOT CHECKED Turn notification on when you post or reply to a topic.
NOT CHECKED When sending notification of a reply to a topic, send the post in the email (but please don't reply to these emails.)
For topics and boards I've requested notification on, notify me of: Replies and moderation
I seems to work now, didn't received too much replies recently, but I saw last one
We shall see, I think everything is OK, just those gremlin's... they are everywhere
