Define your endpoint as follows.

<endpoint name="EP1" template="endPointTemplete"

  uri="http://{system.prop.env}.wso2.com" xmlns="http://ws.apache.org/ns/synapse"/>

it would refer to an endpoint template named as 'endPointTemplate'. The config for it is given below

  <endpoint name="$name">
<address uri="$uri">
<suspendOnFailure>
<progressionFactor>1.0</progressionFactor>
</suspendOnFailure>
<markForSuspension>
