outlook email not being sent.

Hi All,

I am trying to getting into workflow domain. started with the send email task.

created a task

created a container import parameter where i am specifying the email address where to send  the email.

binded this element with the element addresstrings of the email task.

executed the wf and given the email address as input.but no email received.

Q: Do i need to make some email settings SOST or any other ?
Q: i could see the BOR object type for this task by default as SELFITEM and the method as SENDTASKDESCRIPTION. Cant i debug this method when i execute the wf manually?

Thanks
