Email Send/Receive

The email service is only available to registered domain owners and paid hosting users.  Free hosting can receive email being sent to their domain/subdomains but not send email directly from their sites.  Paid hosting can both send and recieve email.
 
Please look to the Awardspace Hosting FAQ for instructions on setting up your email accounts within your Awardspace hosting control panel.
 
The issue about what you as a free hoster can and can't do is a bit convoluted... so I will try to explain it simply.
 

What can be done

Receiving Email

Sending Email

What can't be done

External methods will need to be applied in order for any email not being sent through a mailto link from your site to work. 
 
For forms you can either use an externally hosted form where the host permits sending of the form data to an email address, or you can have the form data sent to a flatfile/*.txt file on your site which you will need to monitor yourself.  You can also have the form open the user's email client (mailto function via submit button) and automatically fill in the details and then the user will have to send the email containing the data from their email client... for you to retrieve.
 
For forum applications or anything which would require user authentication, then this is far more tricky... and to be honest there currently isn't a universal workaround.  It would simply be easier to disable user authentication.
