I seem to be having a problem with mail being unroutable to any address on my system.
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
unrouteable mail domain "aol.com"
This is happening for everything ntl, bt, blueyonder, hotmail and all on addresses that have been in my system and working for months. I at first thought it was a problem with my Nuke site, but now its affecting the shop which is on another database it all started today aswell.
Could someone please investigate domain is calton221.com
