Configure Zimbra to never discard spam messages
I'm trying to make Zimbra (v7.1.2) to NOT discard spam. Reading the administrator guide, I found this is expected to happen:
"Anti-spam Settings: (...) Any message tagged between 33%-75% is considered spam and delivered to the userís junk folder. Messages tagged above 75% are always considered spam and discarded."
I'm making some tests, and spam messages that I send dissapear. I don't know if they dissaper because they are discarded (tagged above 75%) or if something isn't working.
How can I configure Zimbra to NEVER discard messages? I need this to tests, and as a policy, since we need to keep ALL messages, even spam.
Thanks in advance!
