Spam Configuration

• Spam preferences can be set at the Global, Per-Domain, or Per-User levels.
• User settings override Domain settings, and Domain settings override Global settings.
• Each Domain or User can set their own Whitelists and Blacklists.  Whitelists and Blacklists will carry from the top down, so setting a global whitelist will apply to all domains and all users.  Setting a per-domain whitelist will apply to all users at that domain.
  

Spam Reporting

• Raw logs contain pertinent header information for each email.  All hyperlinked entries in the color coded logs can be clicked for quick searching.

• Spam Reports break down Top Senders, Top Domain, and Top Recipients for easy one-click creation of Bad Sender/Recipient Rules, Whitelists, or Blacklists.
