[MM3-users] bounce_score_threshold control

Hi guys,

I have recently started receiving these mails from the system. First it was frighting me out that people's account got disabled, but actually nothing has happened, nobody got disabled. I however looking to figure out how can I control or change settings for this particular mechanism. Please advise me.

emailname@example.it's subscription has been disabled on listname@domain.eu due to their bounce score exceeding the mailing list's bounce_score_threshold.

Regards, Tibor
