32.3.4 Loopback Addresses for Circuit Checking
In order to set up a circuit check message path, you must specify an 
address that will cause a message to be routed in a loop. This may be 
done by sending to a remote address that is configured to then forward 
back to the circuit check address. Or a method that may be more 
convenient in some cases is to specify a form of the circuit check 
facility's own address that embeds the circuit check address within 
some explicit routing components, where the explicit routing components 
will cause routing along the desired path. For instance:
  - When routing through an SMTP host (that allows relaying---note that 
  many SMTP hosts will not allow general relaying), a %-hack 
  address form may be used, as in  or 
   in Example 32-2 above.
  
 - To send into and back out of Message Router, you may send to the 
  circuit check address at the PMDF MRMAN mailbox at the PMDF-MR domain 
  name, as in  in Example 32-2 above.
  
 - To send into and back out of ALL-IN-1 or MailWorks when connected 
  to by PMDF-MR as an MR TS replacement, you should set up an ALL-IN-1 or 
  MailWorks account that is configured to auto-forward back to the 
  circuit check facility and then send to that special account.
  
 - To send a message to an X.400 MTA that the X.400 MTA should then 
  immediately send back to PMDF and the circuit check facility, send to 
  PMDF-X400's own X.400 ORname stem, plus /S=circuitcheck, at the 
  PMDF-X400 pseudodomain name, as in  in 
  Example 32-2 above.
  
 - To loop a message through a PC-LAN mailer, use explicit routing to 
  specify the PMDF system domain name within the PC mailer name space.
  
    - With cc:Mail, specify
  
    
       
      
circuitcheckaddress%PMDFcc:mailpostoffice@cc_local-domain
 
 | 
E.g., 
circuitcheck%domain.com%PMDF@ccmail.domain.com.
     - With Lotus Notes, specify
  
    
       
      
circuitcheckaddress%PMDFlotusdomain@ln_local-domain
 
 | 
E.g., 
circuitcheck%domain.com@PMDF@lnotes.domon.com.
     - With Microsoft Mail, specify
  
    
       
      
PMDFdomain/PMDFpo/circuitcheck@ff_local-domain
 
 | 
     - With GroupWise, specify
  
    
       
      
PMDFwpodomain.PMDFwpopo.circuitcheckaddress@wpo_local-domain

     - With Novell MHS, specify
