To configure the e-mail account edit the <CEP_HOME>/repository/conf/axis2/axis2_client.xml by updating email-address, user-name, password and other relevant property values from the MailTransportSender.

<axisconfig name="AxisJava2.0">
   ... 
   <transportSender name="mailto"
                     class="org.apache.axis2.transport.mail.MailTransportSender">
        <parameter name="mail.smtp.from">email-address</parameter>
        <parameter name="mail.smtp.user">user-name</parameter>
        <parameter name="mail.smtp.password">password</parameter>
