I have also had the same error message (using DSpace 1.3.2) but have not been
able to get to the bottom of it.
I see that someone else had posted to the list in 2007 (
http://www.nabble.com/cant-add-an-item-to-dspace-to13247761.html#a13247859
http://www.nabble.com/cant-add-an-item-to-dspace-to13247761.html#a13247859 )
and only one reply stating to ensure the dspace.cfg settings for email
notification were correct.
If you are able to figure this out, I would also be interested in knowing
what you did to fix it.
