Novell GroupWise 8 Support Pack 2
Novell GroupWise client
Novell GroupWise Post Office Agent


In a GroupWise client you have extra IMAP account that you sync via Send / Receive option. After successful authentication and downloading all new mails, you will see on a POA screen:
Return from IMAP [890F]
There are no errors on a client site, neither it negatively affects a sync of IMAP account.


The problem is caused by a client that sends empty char command upon logout. You will see it after you enable Diag logging level on POA. You will see similar lines like:
13:16:20 736 Processing update: folder record (a3)
13:16:20 736   Locked Database: userual.db
13:16:20 736   Unlocked Database: userual.db
13:16:20 344 Resetting read descriptors
13:16:20 344 Dispatched message for connection #2 protocol (IMAP)
13:16:20 216 IMAP command:[] requested from ::ffff:   User session()
13:16:20 216 Return from IMAP [890F]
