email "sent from the forum" hacked & upgrade (General)
It clearly was spam.
Okay, but that was not my question. If a spam robot insert a new posting to the forum and if you subscribed this thread, too, you get an email from the forum software. This notification message/mail contains the content of the (spam) posting. Again: Do you subscribe threads of the forum?
No, I don't subscribe to threads on the forum.
Plus, the email wasn't sent to me but to another email address.
Like I wrote before, I only saw the email because it wasn't accepted by the ISP of the recepient and because of that bounced to the forum admin email address.
