I use a lot of rules in Outlook to categorize messages I receive. Some rules are based on the sender's address, others based on words in the sender description, and others based on words in the subject. When I want messages based on all three to be marked the same category, I’ve been using three different rules. But I just discovered that “with specific words in the message header” is a broader category that includes a whole lot of information, including all those criteria I was using to organize mail. I was looking for a way to include messages sent “on behalf of” someone, mainly to catch messages sent on behalf of the same entity but using a different mass-mail e-mail address with each message.
