Managing ZCS Configuration > Global IMAP and POP Settings

Global IMAP and POP Settings
IMAP and POP access can be enabled as a global setting or server setting.
With POP3 users can retrieve their mail stored on the Zimbra server and download new mail to their computer. The user’s POP configuration determines if messages are deleted from the Zimbra server.
With IMAP, users can access their mail from any computer as the mail is stored on the Zimbra server.
When you make changes to these settings, you must restart ZCS before the changes take effect.
IMAP and POP3 polling intervals can be set from the COS>Advanced tab. The default is to not set the polling interval.
