Can anyone clarify this? I ask because I am trying to advise my clients on the best way to create personal whitelists using the mail filters under options. My starting point was this article on the ZimbraWiki:

Cool User Spam Filters - ZimbraWiki

so I created a test filter to catch all 'from' 'my contacts', and noticed that it caught everyone in my personal contact and my emailed contacts. Is that the scope and limit of this filter option? What exactly is the definition of 'my contacts'?

btw, I'm new to this forum and forums in general, so if i make any mistakes in etiquette, please let me know.
