Configuring the IMAP4 Server

---

To configure the IMAP4 server:

1. In IMail Administrator, select localhost in the left panel.
2. Expand the Services folder and select IMAP4. The IMAP4 tab appears in the right panel as shown below.
   
3. Enter the options you want to use to configure the IMAP4 server.

   Each option is described at the end of this procedure.

4. Click Apply to save your changes.
5. After making changes, stop the service, wait five to ten seconds and restart the service. Any changes that you make are saved as soon as you click the Stop/Start.

Logging Options

In the Log To box, select the way you want to log IMAP4 events:

• sysMMDD.TXT. This sends event information to a file of this name where mm is the month and dd is the day the log was written. This file is stored in the Spool directory.
• No Log. Select this to turn off the logging of events.
• App Log. This sends event information to the Windows Application Log (viewed with the Windows Event Viewer.)
• Log Server. This sends event information to the Log Server file indicated on the Log Files tab.

Debug Messages. If this is selected, debug messages are written to the log file. This option is resource intensive when using IMAP4.

Force subscribe to public mailboxes. Turn this on to require that the IMAP4 client is subscribed to use a public mailbox. If the user is not a subscriber, he is refused access. Note that subscribing to a mailbox is a protocol command; there is no way for a user to subscribe to a mailbox unless the client application provides this capability.

Force subscribe to private mailboxes. Turn this on to require that the IMAP4 client is subscribed to use a private mailbox. If the user is not a subscriber, he is refused access. Note that subscribing to a mailbox is a protocol command; there is no way for a user to subscribe to a mailbox unless the client application provides this capability.

Server Status. A status message to the left of the Start/Stop button shows the version number, and whether or not the service is running.

Start/Stop Service. This button switches between Start and Stop depending on whether or not the service is running.

Advanced Options

When logging on to IMAP4, the service returns a welcome message that identifies the mail server version, vendor and operating system. Changing the message may help protect your server from spammer or hacker attacks. You can use the IMAP Advanced tab to change the service welcome message, if you wanted to hide the above mentioned information. To revert to the default message, clear this option.

Changing the IMAP 4 Hello Message:

Enter the text you want to be displayed in the IMAP4 service welcome message. The text is limited to 400 characters. If over 400 characters are entered, the default message is used.
