LO52561: UID OUT OF SEQUENCE WHEN ACCESSING MAILFILE VIA IMAP

APAR status

• Closed as user error.

Error description

• The UID of messages get out of sequence when accessing mail
  via
  IMAP.  This may cause issues with certain IMAP clients where
  messages do not display on the client as the client is unable
  to
  determine the next message that has not been seen.
  
  This can be reproduced with the following telnet command after
  logging in and selecting the inbox:
  
  fetch 1:* (UID rfc822.size flags)
  
  A simpler fetch command shows the UIDs in order:
  
  a fetch 1:* uid

Comments

• This APAR is associated with SPR# SRNS85VUFJ.
  Per development:  The IMAP protocol does not require the
   ordering of messages in fetch responses.  UID must be
   allocated in order, and they are for the Domino IMAP server.
   But when responding to commands that specify a message
   sequence set such as 1:*, the IMAP RFC specifies that the IMAP
   server may execute the sequence in any order.  This allows the
   server to return messages in any order it may choose, allowing
   for efficiencies in the response processing.  Any client
   requiring the sequence to be returned in order is not in
   compliance with RFC 3501.
