What are all the strategies/rules/filters/policies/techniques, whatever we call it as, employed by Microsoft Outlook to identify and mark an email as SPAM and moving it to "Junk E-mail" folder?
I'm not talking about the Junk E-mail Options itself available with Outlook like Safe Senders, Safe Recipients, Blocked Senders, etc. but various rules employed by Outlook to mark an email as SPAM and moving it to Junk E-mail folder.
Any relevant links on the same are also appreciated. I hope there is a Microsoft Support knowledgebase article on this, but I don't have them handy with me now.
Experts idea/suggestion are welcome.
NOTE: The question is common across available Office versions - 2000, 2003, 2007
