sending emails from the enterprise library 5 from hosted enviroment

Question

Hi there, I am building a .net 4 application and I am wanting to use the enterprise library 5 for my error handling.

I am trying to setup email however I cant get it to work on my hosted enviroment. I can get it work locally however no emails are been triggered on the live enviroment.

I have setup my web.config to look something like this

 <mailSettings>
  <!--<smtp deliveryMethod="SpecifiedPickupDirectory">
            <specifiedPickupDirectory pickupDirectoryLocation="c:\maildrop" />
        </smtp>-->
  <smtp from="[email protected]">
    <network host="localhost"/>
  </smtp>
</mailSettings>

The listeners settings look like

   <add name="Email Trace Listener" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.EmailTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=null"
    listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.EmailTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=null"
    toAddress="[email protected]" fromAddress="[email protected]"
    subjectLineStarter="ERROR!!" smtpServer="localhost" smtpPort="25"
    formatter="Text Formatter" authenticationMode="None" />

Do I need to do some extra steps to get the enterprise library to send emails? I have tested sending an email using system.net and I am able to send emails ok.
