Subject: RE: how to support pop ,notes,web mail client at same time
You pick POP3 for a user only using POP3, etc.
From the help:
Each POP3 user must have a mail file on the IBM® Domino® server. You can create the mail file automatically during user registration, or you can manually create a mail file. If the user is already a registered IBM Notes® user who has an existing Notes mail file and if you set up the Person document to use POP3 as the mail system, the user can use a POP3 client to access the mail file.
To support access from IMAP clients, mail files must be specially modified to store IMAP folder and message attributes as database items. If you used the Domino® registration process to create a user, and set the user’s mail system type to IMAP, Domino automatically performs the steps required to prepare the mail file for IMAP use. Otherwise, you must complete several tasks to prepare a mail file to support IMAP access.
IMAP clients display certain folders and views in a mail file differently from Notes® clients. For instance, from an IMAP client, the Sent and Draft views, the Inbox and Trash folders, and any public folders appear as IMAP mailboxes. Also, hidden and private folders are not visible to IMAP clients.
Previously, synchronization between the IMAP Sent, Draft, Inbox, and Trash mailboxes and the Notes client Sent and Draft views and Inbox and Trash folders was not available. However, in this release of Domino, as the administrator, you can set a NOTES.INI parameter to enable synchronization between these IMAP mailboxes and the corresponding Notes client views and folders.
The Domino IMAP service does not support renaming of the Inbox folder in a Notes mail file from an IMAP client.
For users who access their mail files from both an IMAP client and a Notes client, Domino synchronizes unread message marks between the two. Thus, a message marked as read in Notes is also marked as read for an IMAP client, and vice versa.
IMAP clients cannot read messages that use Notes encryption. IMAP clients do not have access to the Notes private key needed to decrypt messages encrypted with a user’s Notes public key certificate. As a result, when a user opens an encrypted Notes message from an IMAP client, only the unencrypted header information is available. The server replaces the blank message body with the following text:
[Portions of this MIME document are encrypted with a Notes certificate and cannot be read.]
The adminstrator at your company should be able to help you more.
