回答1:

if you want to get the email address from a property value then use the header mediator to set value of "To" to "mailto:faisal.shaik@youtility.in".

You can do that adding the following before the send mediator

<header name="To" expression="fn:concat('mailto:', get-property('Mail'))"/>

回答2:

You can use this:

<property name="To" expression="get-property('uri.var.to')" scope="transport"/>
<send>
    <endpoint>
        <address uri="mailto:"/>
     </endpoint>
</send>

回答3:

   <send>
             <address uri="mailto:xxx@yyy"/>
         </send>

key-expression also can be used..
