Configuring the IMAP4 Server
To configure the IMAP4 server:
- In IMail Administrator, select localhost in the left panel.
- Expand the Services folder and select IMAP4. The IMAP4 tab appears in the right panel.
- Each option is described at the end of this procedure.
- Click Apply to save your changes.
- 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 Stop/Start.
Logging Options
In the Log To box, select the way you want to log IMAP4 events:
- sysMMDD.TXT. Select to send 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 to turn off the event logging.
- App Log. Select to send event information to the Windows Application Log (viewed with the Windows Event Viewer.)
- Log Server. Select to send event information to the Log Server file indicated on the Log Files tab.
Other Options
Debug Messages. Select to write debug messages to the log file for debugging IMAP4 problems. This option is resource intensive.
Force subscribe to public mailboxes. Select to require the IMAP4 client to subscribe to use a public mailbox. If a user is not a subscriber, he is refused access.
Force subscribe to private mailboxes. Select 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: The client email application must support the IMAP4 protocol to successfully use the force subscribe to public or private mailboxes. Enable Dedicated SSL Listener. Select to enable a dedicated port that accepts only SSL encrypted connections from the IMAP4 service. You can change the default port used by the SSL Listener in the SSL Port box.
SSL Port. (default port is 993) Enter the port used by the dedicated SSL Listener to accept connections.
Enable TLS. Select to enable the IMAP4 service to accept SSL/TLS connections over the IMAP4 port through use of the STARTTLS command.
Disable unsecure login. Select to enable IMAP4 service to only accept SSL logins or logins after the STARTTLS command has been initiated.
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. The 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.
