Hi,

After upgrading from 3.0.15 to 3.0.17 sending email stopped working. 
I don't know why, and i cant really debug the problem. 

I'm certain that my SMTP settings are correct, aswell as the notifications/email part of umbracoSettings.config.

I upgraded with the UmbracoContour_3.0.17_update.zip package. 

I've tried both "network" and "specifiedPickupDirectory" as deliveryMethod in system.net/mailSettings/smtp with valid configurations - working with a simple System.Net.Mail.SmtpClient.Send() and w/ umbraco.library.Send(). Also, the umbracoLog doesn't log anything. 

In web.config I've got these settings:

<system.web>
    <httpModules>
      <add name="ContourFormBuilderHttpModule" type="Umbraco.Forms.CodeFirst.ContourFormBuilderHttpModule, Umbraco.Forms.CodeFirst" />
    </httpModules>
</system.web>
<system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
      <add name="ContourFormBuilderHttpModule" type="Umbraco.Forms.CodeFirst.ContourFormBuilderHttpModule, Umbraco.Forms.CodeFirst" /> 
    </modules>
</system.webServer>
<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="4.0.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Extensions.Design" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="4.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
</runtime> 

Is there any settings i've missed?

What can i do to debug it?
Can I adjust the verbosity of the log?
