Can anyone tell me where to change the proxy server settings for the Zimbra Desktop under Linux? Every day a short time after I launch the Zimbra Desktop I am prompted for a user name and password for my proxy server. This makes sense because the proxy server that it is using requires authentication. However, I'd like to change the proxy settings to another server that does not require authentication and I can't seem to find where this setting lives. I thought it might be tied to another program's settings, but I've checked my .bashrc, Firefox, Konqueror, and Opera but none of them are using this particular proxy server. I've disabled auto updates in the preferences.js file, but I still get prompted at least once a day for the user name and password.
