Maybe his new IP is not a valid relay client ?
If he is using Outlook or Exchange you should try instead using the MS
Internet Mail client (from IE) or Messenger from Netscape (not sure about
Eudora) from his PC both of these will tell you what error is returned from
the server. (ie. sorry, ...rcpthosts.. #5.7.1 or some other message)
If he's using Outlook it doesn't really say what error is returned from the
server. ie. when my rcpthosts was failing all I got in Outlook was a
message returned saying:
The following recipient(s) could not be reached:
(...)
No transport provider was available for delivery to this
recipient.
