Mail to Comcast is rejected and is returned with an error message
containing the code BL004. What does this mean?

Our filters have determined that email from your mail server has been
sent in patterns which are characteristic of spam.  In an effort to
protect subscribers, your mail server has been blocked from sending
email to the Comcast network.  Mail servers are typically shared by
many users so it may be the case that another party using your mail
server has sent spam, even if you have not.
