send email exteneded action is not working

Jun 26, 2012 at 2:41 PM

I added and deployed the UsefulSPDWorkflowActivities_0.5.0 wsp to my sharepoint site.

It has appeared in Manage features of central admin and even in the Actions of SPD.

I used the action "send email extended" in my workflow , but it is not sending any mails.

I even find the entries in the web.config under <authorizedTypes> and <SafeControls> tags.

outgoing email configuration is also fine because default "send email" action is working

Please........... provide the solution ASAP.
