If the message is a hard bounce or Spam the owners email setting are automatically switched to off as if we continue to send to the email address our server may be put on a spam black list which would effect everyones email.
If we receive a Hard Bounce or a Spam message, we need to automatically turn the contacts to off, if we continue to try and send mail to the address after hard bounce or Spam message our mail servers could be put on a blacklist and all email would be rejected.
The notifications column will indicated if the contacts settings have been changed, you may wish to contact this person and ask if they have a new email address.
