Zimbra Proxy Server > Zimbra IMAP/POP Proxy

Zimbra IMAP/POP Proxy
Zimbra IMAP/POP Proxy allows end users to access their ZCS account using end clients such as Microsoft Outlook, Mozilla Thunderbird, or other POP/IMAP end-client software. End users can connect using POP3, IMAP, POP3S (Secure POP3), or IMAPS (Secure IMAP).
For example, proxying allows users to enter imap.example.com as their IMAP server. The proxy running on imap.example.com inspects their IMAP traffic, does a lookup to determine which backend mailbox server a user’s mailbox lives on and transparently proxies the connection from user’s IMAP client to the correct mailbox server.
Zimbra Proxy Ports for POP and IMAP
The following ports are used either by Zimbra Proxy or by Zimbra Mailbox. If you have any other services running on these ports, turn them off.
End clients connect directly to Zimbra Proxy, using the Zimbra Proxy Ports. Zimbra Proxy connects to the Route Lookup Handler or Zimbra Mailbox using the Zimbra Mailbox Ports.
 
Setting Up IMAP and POP Proxy After HTTP Proxy Installation
Zimbra IMAP proxy is installed with ZCS and set up during installation from the ZCS configuration menus. To set up the HTTP proxy, Zimbra proxy must be installed on the identified proxy nodes in order to set up HTTP proxy. No other configuration is usually required.
If you need to set up IMAP/POP proxy after you have already installed Zimbra HTTP proxy, and set up the Zimbra mailbox server and the proxy node.
Note:
You can run the command as zmproxyconfig -r, to run against a remote host. This requires the server to be properly configured in the LDAP master.

If your configuration includes a separate proxy server, you must do the following.
1.
/opt/zimbra/libexec/zmproxyconfig -e -m -H mailbox.node.service.hostname
