To integrate Zimbra with Gmail, you can follow these general steps:
Enable IMAP Access in Zimbra: Log in to the Zimbra Administration Console and navigate to the COS (Class of Service) settings. Ensure that IMAP access is enabled for the desired Zimbra mailboxes that you want to integrate with Gmail.
Configure Gmail Account: Log in to your Gmail account and go to the Settings. Navigate to the "Accounts and Import" or "Accounts" tab, depending on your Gmail version.
Add Zimbra Account in Gmail: In the "Check mail from other accounts" section, click on "Add a mail account." Enter the email address of your Zimbra account and click "Next."
Configure Zimbra Account Settings: Enter the necessary information for your Zimbra account, including the incoming mail server (IMAP), port number, and security settings. Provide your Zimbra email address and password. You may also specify whether to leave a copy of retrieved messages on the server or not.
Choose Import Options: Select the import options based on your preferences. You can choose to import all existing Zimbra emails into Gmail or import only new emails received after the integration.
Verify Settings: Gmail will attempt to connect to your Zimbra account using the provided settings. Ensure that the connection is successful, and Gmail is able to access your Zimbra mailbox.
Send As Zimbra Account: To send emails from Gmail using your Zimbra email address, you can configure Gmail's "Send mail as" feature. This allows you to compose emails in Gmail and have them sent to your Zimbra email address.
Test and Verify Integration: Send a test email from Gmail to your Zimbra account and vice versa to ensure that emails are being synchronized correctly. Verify that you can access and manage your Zimbra emails directly from Gmail.
