Answer 1

That's quite simple, below is the code.

 <switch source="get-property('axis2','HTTP_SC')">
                    <case regex="200"><!-- Do not do anything here as it's success -->
                        <log description="200log" level="custom">
                            <property expression="$ctx:ERROR_CODE" name="200reserrorcode"/>

                        </log>
                    </case>

                    <default><!-- Put your logic here to send mail -->
                        <log description="reslog" level="custom">
                            <property expression="$ctx:ERROR_CODE" name="reserrorcode"/>
                            <property expression="$ctx:ERROR_MESSAGE" name="reserrormessage"/>
                            <property expression="get-property('axis2','HTTP_SC')" name="reshttpsc"/>
                        </log>
                    </default>
                </switch>
