I post a daily blog on music education related topics. Each night after I post the blog I email a copy of it to a subscriber list. Everything has been fine until tonight. Suddenly I am getting several bounced emails with explanations stating that the message has been flagged as spam. In some of the replies it lists the reasons, including keywords that don't appear anywhere in my newsletter. This is one of the bounce replies I received: Here is another that listed the words it used to blacklist my mailing: The thing is that NONE of those spam words appear anywhere in my message. I even checked the raw HTML to make sure that I had not been hijacked in some way. Can anyone tell me what I should (or could) do about this? I have been sending out this newsletter for over a year and this is the first time it has happened. Sincerely, MaestroC
