in our Zimbra 8.6 Single Server Installation we opend Port 443 from external to be able to use Active Sync for Mobile Devices.
But by doing this, everybody is able to Login to Webaccess via Internet, because it is the same Port (Port 443).
Proxy is enabled, so intern we can ouse Port 8443 to Access Webmail, an from external, wie use 443.
Is there a way tu use two different ports for Active Sync and for Webmail? Active Sync is already enabled only to that kind of users, who should be able to use this.
And for webmail It souldn´t be possible for every user to remote login to his Mailaccount via internet.
