IMAP Settings

How to get here

Note: At the top of each Services page, the name of the Service, its Status (Running or Stopped), and a Start/Stop button appears. This allows you to Start or Stop individual Services from their respective web pages, as well as from the Service Administration page.

You can use the IMAP Settings page to configure the IMAP Server. IMAP 4 lets users access remote messages stored on the mail server as if they were local. Users can read, move, delete mail, create mailboxes on the server system. Since messages reside on the server, users can access their mailboxes from multiple machines.

Important: After making changes, click Save. Stop the service, wait 5-10 seconds and restart the service.

• Save Logs To. Choose one of the following from the list box.
  • No Log. Select this option to turn off event logging.
  • 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.
  • Log Server. Select to send event information to the Log file indicated on the Logging tab.
  • Debug Messages. Select the check box to write debug messages to the log file for debugging IMAP4 problems. This option is resource intensive.
• Force Subscribe to Private Mailboxes. Select the check box to require the IMAP4 client to subscribe to use a private mailbox. A user who is not a subscriber is refused access. Do not enable this option if you wish to use web messaging.  Choose this option if users are using Outlook or another client.
• Force Subscribe to Public Mailboxes. Select the check box to require the IMAP4 client to subscribe to use a public mailbox. A user who is not a subscriber is refused access.
• Allow Unsecured Access. Select the check box to allow users to login to the system without authenticating via secure mode (such as SSL ).

SSL Settings

Note: IMail Server uses OpenSSL Command Line Tool (v0.9.8e) which supports up to 4096-bit RSA and 2048-bit DSA. OpenSSL is a cryptography toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) network protocols and related cryptography standards required by them.

• Enable SSL. Select the check box 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. Enter the port used by the dedicated SSL Listener to accept connections. The default IMAP4 SSL port is 993; the valid range is from 1 - 32,000.
• Enable TLS. Select the check box to enable the IMAP4 service to accept SSL/TLS connections over the IMAP4 port through use of the STARTTLS command.

Advanced Options

When logging on to IMAP4 , the service returns a welcome message that identifies the mail server version and vendor. You can use the IMAP Advanced options to change the service's welcome message, for example, if you want to hide the mail server version and vendor information.

• Hello Message. Enter the text you want display in the IMAP service welcome message. The text is limited to 400 characters or less. If  you enter over 400 characters, the system uses the default message. To intentionally revert back to the default message, clear this field.

Save. Click to save your settings. An "Update Successful" message and the time of the update appears.
