554 Error writing message to safe storage; unable to append local content to message (in reply to end of DATA command)

Since I did not find the answer for this error here in Notes.Net, I spoke with IBM, and they advised me that it was a bug in DOmino 6.5.2 and here is the document containing the workaround until the upgrade can occur.
