I sent an e-mail through Outlook to a coworker with a subject line that we both know that it is not work related. I am on dial up acroos the city and the location they are at they use Sprint DSL with our company name as the @part.com. I got a read receipt back that states someone other than the person I sent it to read it. It said so and so on behalf of a (which is the first initial of her name didnt really say her full name) read the e-mail with that subject line that we know is non work related. Does that mean that person read the e-mail? If so is there a way to prevent that?
