Mail being flagged with "CM SPAM detection: spam"

[LeoC2]

Suddenly my outgoing emails all have "CM SPAM detection: spam" at the top of the message.

Anyone have an idea what's going on here? The latest was sent referencing a web page http://nyautofest.com/NYAF/news/extra.html

I do not use MLM

It is your server spam filter, without doubts.
