Question : Remote host said: 550 You are not allowed to send mail

Save me please.

How interesting.  It does say 2006 at the top, but it says 2005 at the bottom.  And most importantly, the status.  Lock and hold basically mean, it has expired but your registrar is holding it for you to renew.  Do that quick, that doesn't last long!!
