A message that you sent could not be delivered to all of its recipients.

NOTE: And this is important - Junk Email Filter is a front end spam filtering service. We accept email for our customers, filter it, and pass the good email on. Sometimes when we forward email as good the server we forward to rejects it. Generally if you are getting this message it is because the server we forwarded to  * NOT JUNK EMAIL FILTER * has rejected the message.

If you see below the phrase "error from remote mail server" then it is the server who we are forwarding to, NOT US who is rejecting the email. Read the reason carefully and see if you can correct the cause of the rejection.
