We use the old-fashioned 55x codes and always supply a plain-text explanation. I can also assure you that we have been getting our spam all weekend without any hints of slowdown ;-) Come to think about it, I took that server down for maintenance yesterday, for about an hour I would say. But that was several hours after the time stamp in your error report. Eric
