Public folder prefixThe name of the virtual root folder IBM® Lotus® Domino™ uses to organize the hierarchy of IBM® Lotus(T) Notes® mail databases configured as IMAP public folders. When an IMAP client connects to the server it displays the public folders available to the user as subfolders of this folder.

Unless you have a specific reason to change the folder prefix, accept the default name to ensure IMAP clients can access public folders on the server.

Public folder database linksDatabase links for Notes mail databases that you have enabled for IMAP access. To designate a mail database as an IMAP public folder, copy its database link and paste it into this field.

Note To be configured as a public folder, a database must be created from a Notes mail template. The IMAP service does not support the use of NNTP or discussion databases as IMAP public folders. To open the specified database from an IMAP client, the user must be granted appropriate access privileges in the database ACL.

Other users' folder prefixThe name of the virtual root folder which contains organizes IBM® Lotus® Notes® mail databases whose owners delegated access to other users. When an IMAP client connects to the server it displays the other users' folders to whom the user has access as subfolders of this folder.

Unless you have a specific reason to change the folder prefix, accept the default name to ensure IMAP clients can access other users' folders on the server.

Other users's domain delimiterThe character that Domino uses to separate the common name, organizational unit(s), and organization name in a users' Notes hierarchical names when displaying the user's mail file to an IMAP client as part of the Other users' folder list. Default is forward slash ( / ). Enter a different character if IMAP clients that connect to this server cannot display Notes hierarchical names that contain the default separator character.

For example, if you enter the pipe character ( | ), Domino sends the mail folder of a user named Jada Mendez/Westford/IBM to IMAP clients as Jada Mendez|Westford|IBM.

IMAP users who can change other users' unread marksThe fully-qualified Notes names of users to whom you give permission to change the unread status of messages in other users' mail files. The user name may represent an application running on the server. Notes groups are valid entries in this field.
