This is a message I just sent to [log in to unmask]: Dear Rocketmail- I run a very heavily used mailing list for the medical condition fibromyalgia, It's called FIBROM-L. I recently discovered that your mailer automatically adds a signature advertising yahoo.com mail. Our mailing list does not allow advertisements of any sort, and we can't make any exceptions. No person using a rocketmail account will be allowed to post to our mailing list, and I am going to encourage other mailing list owners to do the same thing. Sincerely Yours Mark London
