Send email as HTML

[teognost]

Hi
I need to implement in VBuild this steps from NANT:
<target name="MailNightlyReport">
<mail mailhost="${mail.smtp.server}" from="${mail.from}" cclist="${mail.complete.results.cclist}" tolist="${mail.cclist}" subject="Nightly build result: ${build.result.string} [${assembly.version}]" format="Html" failonerror="false">
<files>
<include name="${console.outputs.location}\index.html"/>
</files>
</mail>
</target>
Basically I need to send an email as HTML but I am not sure how to do this in VBP.I see in the step Send Mail ->the option Send as HTML but how can I load into Message section the file index.html being created at run time (when VBP is running)?
