LO46161: POP3 RETURNS WRONG NUMBER OF AVAILABLE MESSAGES WHEN THEY HAVE P REVIOUSLY BEEN DOWNLOADED USING TOP COMMAND

APAR status

• Closed as program error.

Error description

• POP3 returns wrong number of available messages when they have
  previously been downloaded using TOP command
  
  When a POP3 client uses the TOP command to retrieve a message,
  this message will not be available for download any more in
  further session, until a new mail comes in the mail database or
  the
  POP3 task gets restarted.
  
  Steps to reproduce
  
  1-Build a standard Domino 8.0.2 FP2 with no specific Notes.ini
  parameter (also reproduced on 656 / 704 / 850 / 851)
  2-Create a new user named POP, and restart the Domino server
  3-Have your admin user send a mail to this new user POP
  4-Load the POP3 task
  5-Access the POP database using POP3 / Telnet :
   Telnet ServerIP 110
   User POP
   Pass Password
   =>The server will respond "+OK pop has 1 messages"
  6-Download the message using the TOP command :
   Top 1
  7-Stop the POP session :
   Quit
  8-Log in the same database again
   Telnet ServerIP 110
   User POP
   Pass Password
   =>The server will respond "+OK pop has 0 messages"
   Quit
  
  As per the previous description, the Server has no POP3 specific
  notes.ini parameter, so the mail should not be considered READ
  (since it would require the parameter POP3MarkRead=1)
  Therefore, the message should still be available. As a matter of
  fact, using the Notes Client, the message appears unread.
  
  9-Using your admin user / database, send a new mail to user
  POP
  10-Log in the POP database again
   Telnet ServerIP 110
   User POP
   Pass Password
   =>The server will respond "+OK pop has 2 messages"
  
  The 2 messages are now both available.
  We see that a new message coming in set the proper amount of
  available messages back on track. The following steps show that
  restarting the POP3 task also has the same effect
  
  11-Download another message with the Top Command :
   Top1
  12-Stop the POP3 session
   Quit
  13-Log into the same database again
   Telnet ServerIP 110
   User POP
   Pass Password
   =>The server will respond "+OK pop has 1 messages"
   Quit
  
  Despite the fact there are 2 available messages in the DB, POP3
  only shows 1
  
  14-From the Domino Console, restart the POP3 task
  15-Log into the same database again L
   Telnet ServerIP 110
   User POP
   Pass Password
   =>The server will respond "+OK pop has 2 messages"
   Quit
  
  
  Other Info:
  Might be related to SPR BMGN6YWRML but it is supposed to be
  fixed in 8.5.1 while I could reproduce the problem on this
  version too.
  Also, I did not use the JAVA mail API but a standard TELNET /
  POP3 session.
  

Local fix

• The RETR command does not show such a problem : the amount of
  available messages is always correct
  

Problem summary

• A programming error was found and will be corrected in a future
   release.
  

Problem conclusion

• A programming error was found and will be corrected in a future
   release.
