In addition to local addresses, you can route all your connections through proxy servers. The email server would see the proxy server's IP address as the client IP.
EmailEngine supports HTTP CONNECT-based proxies and SOCKS proxies (versions 4 and 5).
The format of the Proxy URL is the following:
Example HTTP proxy with username and password (if the server is using a standard HTTP or HTTPS port, then you do not have to specify it):
Example SOCKS5 proxy url:
Option 1 – global proxy
On the same network configuration page, as shown above, you can also set up a global proxy. In that case, all connections, both for IMAP and SMTP, would be proxied through this specific proxy server. This is primarily useful when your network is private, and you have to make requests through a dedicated proxy server with a public interface.
Option 2 – account specific proxies
Another option is to set up account-specific proxies. When creating or updating an account, use the
proxy property that takes the proxy URL as its value.
