I just got six similar email messages from one new message, sent at 20.09, 20.11, 20.13, 20.16, 20.20, 20.26. There doesn’t seem to be a clear interval here.
- my email account: six messages of the same type
- email logs of Discourse, there was only one sent (type: user_posted)
- logs of mailgun: six messages Accpeted & Delivered
Read: something caused the sending to take place multiple times.
