junk mail list no no's

Microsoft has a list of its filters it used to determine if something should go to the junkmail folder of outlook (or adult folder if set up).  I am sure this isn't a definitive list, but it is always good if you are sending out an important email to double check.  A few of these could easily catch harmless - nonspam - email.  I have to believe the list is larger than this.  I did a number of searches and found updates for 2003, a few guides to adding/removing your own filters, and that is about it.

Items include:

Body contains "Dear friend"
Body contains "for free?"

and From contains "sales@"
