FW: I-D ACTION:draft-gahrns-imap-login-referrals-00.txt

["Mike Gahrns (Exchange)" <[e-mail]>]

These 2 internet drafts are now available.

I do not expect much further discussion on them, as they are essentially
unchanged from the previous IMAP-referrals-02 draft.   I incorporated
the following minor changes that were requested:

1) Split the draft into 2 seperate drafts:  A mailbox referrals draft
and a login referrals draft.
2) Added user;AUTH=* in examples as per changes to IMAP URL draft
3) Introduced the RLIST and RLSUB command to avoid displaying to a non
MAILBOX-REFERRALS enabled client inaccessible mailboxes.
4) Referral Response code returned in tagged NO instead of untagged NO.

A New Internet-Draft is available from the on-line Internet-Drafts 
 directories.


       Title     : IMAP4 Mailbox Referrals

       Author(s) : M. Gahrns

When dealing with large amounts of users, messages and geographically 
dispersed IMAP4 [RFC-2060] servers, it is often desirable to distribute 
messages amongst different servers within an organization.  For example
an 
administrator may choose to store user's personal mailboxes on a local 
IMAP4 server, while storing shared mailboxes remotely on another server.

This type of configuration is common when it is uneconomical to store
all 
data centrally due to limited bandwidth or disk resources.        
         
Mailbox referrals allow clients to seamlessly access mailboxes that are 
distributed across several IMAP4 servers.         

A referral mechanism can provide efficiencies over the alternative 
"proxy method", in which the local IMAP4 server contacts the 
remote server on behalf of the client, and then transfers the data 
from the remote server to itself, and then on to the client.  The 
referral mechanism's direct client connection to the remote 
server is often a more efficient use of bandwidth, and does not 
require the local server to impersonate the client when 
authenticating to the remote server.


Internet-Drafts are available by anonymous FTP.  Login with the username
"anonymous" and a password of your e-mail address.  After logging in,
type "cd internet-drafts" and then
     "get draft-gahrns-imap-mailbox-referral-00.txt".
A URL for the Internet-Draft is:

Internet-Drafts are also available by mail.	
	                                                
Send a message to:  [e-mail]. In the body type: 
     "FILE /internet-drafts/draft-gahrns-imap-mailbox-referral-00.txt".
							
NOTE: The mail server at ds.internic.net can return the document in
      MIME-encoded form by using the "mpack" utility.  To use this
      feature, insert the command "ENCODING mime" before the "FILE"
      command.  To decode the response(s), you will need "munpack" or
      a MIME-compliant mail reader.  Different MIME-compliant mail
readers
      exhibit different behavior, especially when dealing with
      "multipart" MIME messages (i.e., documents which have been split
      up into multiple messages), so check your local documentation on
      how to manipulate these messages.
