Whats my Whitelist all about?
Your whitelist lets you specify that mail coming from specific senders (or entire domains) should not be spam-checked, and should be delivered to you regardless of its content. It’s a way of making sure that you don’t inadvertently block mail from people you know and trust. We encourage you to only use whitelists and blacklists as a last resort since doing so will bypass the “learning” component of the PostGuard filter.
