open new message in default email client

Hi,

We often have to send mails to participants of courses, that are unique. Therefore we need to be able to open a new message in the default mail client of the pc and have the selected emails inserted. Presently we do this by having a custom action in the report, that creates a comma separated list with the selected emails. This list is then passed to a Page where it is formatted as mailto link:

htmlpage Mailadressen(emails)
<%{%> <a href='mailto:<%=emails%>'>Hier klicken um Mail zu erstellen</a><%}%>

The user can then click on the link to open a new message with all the email adresses.

I was wondering if there is way to avoid going through the step of creating a Page with a mailto link and instead open an email message directly in the enail client from the custom action? I have tried using openurl() with the mailto as url, but this does not work. Maybe someone has a suggestion?

Thanks,

Michel
