Yahoo still blocking mail

We’ve narrowed down what caused the blockage.  A user who forwards all his mail to Yahoo fired off several thousand jobs on the TeraGrid, all of which started failing, resulting in a near-constant flood of mail to that user.  Yahoo interpreted this as a Denial of Service or Spam flood and blocked out mail servers.  We’re still trying to get the block removed.Forwarding your mail offsite is a bad idea for a great number of reasons, a big one being that we can’t help you when things go wrong.  This particular situation is an example of one in which we have no control, we’re at the whims of Yahoo.  And right now, any user who is forwarding his mail to Yahoo isn’t getting anything from us.More updates as they are warranted…
