This is not as a serious a problem as are Replies and reports on non-probes. See 
“Considerations” later in this section for more information.
Incoming Probes
After the TRANSFER Gateway detects that the incoming message is a probe, it checks 
the existence of each O/R Name for which it is responsible.
The Gateway checks to see if there is an XDIR server configured. If one is present, the 
Gateway passes each O/R Name to the XDIR server and retrieves the transformed name.
If there is not an XDIR, the Gateway combines the O/R Name's Surname and OrigName 
fields to get the traditional CORR @NODE recipient name.
Having the TRANSFER name, converted by either method, the Gateway then uses 
READ^NEXT^NAME UOW to verify the existence of the Recipient.
If READ^NEXT^NAME can locate the Recipient, then the Gateway returns a Delivery 
report for that recipient if the Delivery report flag is set for that O/R Name.
If READ^NEXT^NAME cannot locate the Recipient, then the Gateway returns a Non-
Delivery report for that recipient, using the Reason/Diagnostic codes following.
Mapping of potential TRANSFER errors when attempting a READ^NEXT^NAME on 
an incoming probe involves these codes:
Node unavailable (but does exists): 
Reason: Transfer Failure (Comm failure) 
Diagnostic: NA
Name ambiguous 
Reason: Unable to Transfer 
Diagnostic: Ambiguous OR Name
Name not found (node exists, but name does not exist at node)
Reason: Unable to Transfer 
Diagnostic: Unrecognized OR Name
Name Server not found (node exists, but no TRANSFER sys)
Reason: Directory Operation Unsuccessful 
Diagnostic: NA
Node does not exist: 
Reason: Directory Operation Unsuccessful 
Diagnostic: NA
Distribution List does not exist: 
Reason: Unable to Transfer 
Diagnostic: DL-Expansion failure
Non-Support in TRANSFER Clients 
No mechanism using current TRANSFER clients, such as M6530, exists to set the probe 
flag or to create a TRANSFER probe.
