My users have got some POP3 external accounts set up. The only way the external accounts get checked is when using the WebUI and hit the "Get mail" button.
I thought there would be a way to check on a regular basis, i.e. following the "Polling interval (minutes after which to check for new mail)" parameter, accessible in the options.
Is it something out of scope of Zimbra 4.5.1 or a misconfiguration?
