I am not an admin of the discourse instance.
As for the bounces, the thing is there has been none, unless my server
started sending NDN just to Discourse. There have been delayed mail
notifications, but these are not NDN.
As for succesful emails, discourse has tried to send no mail to my
machine between Nov 30 and Dec 14, so I don’t really see how successful
emails could have reduced the bounce score over time. Unless ~10 hours
sending one delayed mail per received mail is already enough to pass
over the point of no return? nixos1@discoursemail.com sends about 20
mails per day, so I guess that’s about the number of delayed mail
notices my server sent.
However, I just want to insist that the thing I consider a bug is that
mail delay notices appear to be considered as mail bounces, which is
not true.
They should just be ignored, especially for dead address detection
reason where it makes sense to wait for an actual bounce. Indeed, I did
eventually receive all the email discourse sent me this day (but not
email discourse stopped sending me after noticing the delay
notifications)
