RegEx in XenMobile Netscaler Connector

By default you cannot use regex in XenMobile NetScaler Connector (XNC) which may pose a challenge if you wish to whitelist a certain mail client (i.e. WorxMail) to access ActiveSync

However Citrix have a private build of the binaries that provide regex functionality, in order to enable regex you need to raise a case with Citrix and request the private build
