Why should I use this product? I'm a Manager user and I have permission 
in the current folder where the object's is to Use MailHost Services , 
Add Documents, Images, and Files 
<http://localhost:8080/AtestFordelete/attachment_test/manage_permissionForm?permission_to_manage=Add%20Documents%2C%20Images%2C%20and%20Files> 
and Change Images and Files 
<http://localhost:8080/AtestFordelete/attachment_test/manage_permissionForm?permission_to_manage=Change%20Images%20and%20Files>
I change the python script code to :
  
from email.MIMEBase import MIMEBase
msg=container.my_mt.as_message(
          mfrom='webmaster at example.com',
          mto='nicolasg at gmail.com',
          message='This is a test!',
          subject='Attempt 100 !')
msg.send()

*have removed the ->msg.add_file(container['myfile.bin']) and Zope 
prompts for user name and password. Whatever I write (correct login or 
not) it keeps prompting the same.
If  I choose cancel your product show me the current message:

<strong>Error Type: Unauthorized</strong><br/>
 <strong>Error Value: You are not allowed to access 'send' in this 
context</strong><br/>

No error is reported in the error log...
