How to trace andriod device connecting without worx

Hi,

I know this is not right forum for worx client question as its citrix product. I have worx (MDM ENV) for clients who install it on android devices and use active sync.

I came to know from few users that few android user can bypass and access active sync without this worx. I know there are few third party tools like "Blue Mail" which provide such features. so i have few question and expect answers

1) How we can stop blue mail access in our ENV (Have TMG as proxy)

2) How to trace which users is connecting without worx from android and how to block it.
