objectclass rfc822Delivery

[Kristina <kristina@fsas.fujitsu.co.jp>]

I would like to know whether

°・．。*.°・．。・.°・．。・.°*。・．。・...゜☆¨・．。・.°゜・。
Question 1)  Openldap(I have the latest stable version) recognizes the rfc82
2 objectclass 
or do I have to define it somewhere first??  If I need to define it, is it d
one at 
slapd.oc.conf , slapd.oc.conf.default or neither??  How do I define it?
This is a description of the objectclass at:
http://www.stanford.edu/group/networking/directory/doc/NotesOnDITDesign-22-O
ct-1998.txt
*******
  rfc822Delivery Object Class

   ( 1.3.6.1.4.1.299.1
       NAME 'rfc822Delivery'
       SUP top
       STRUCTURAL
       MUST rfc822ForwardingMailbox
       MAY (
           generalID $ mailAcceptingGeneralID $ preferredGeneralID $
           personalPOBox
       )
   )
*****
and similar description for the possible attributes such as mailAcceptingGen
eralID.
How do I use the above info and where do I put it in LDAP, if I have to!??

°・．。*.°・．。・.°・．。・.°*。・．。・...゜☆¨・．。・.°゜・。
Question 2) Is rfc822Delivery objectclass the only objectclass I require to 
route 
email from the mail hub to the other mail servers.  The document at:
http://www.stanford.edu/~hodges/doc/draft-ietf-asid-email-routing-su-00.txt

talks about other objectclasses such as the 
SUrfc822Routing object class and SUmailDrop attribute??!!!!

Help me!!
