[Zope] how to send a mail attachment with python (ZPT) ?

[Georgakopoulos Nicolas]

I want to send values from a form by mail but I want to make this values 
a file and then send that file as an attachment.
1.How can I make the values of the form to a file (maybe text file) ?
2.If I make that file how can I send it by mail as an attachment ?

My code for simple mail message  is (mailAction.py) :

# locate the mailhost
mailhost=container['mailhost']

# email message settings
recipient='someone at mail.com'
sender='fromMe at mail.com
subject='This is a test mail'

# format the email message
message='this is my message body...'

# send the message
mailhost.simple_send(recipient, sender, subject, message)

# return a confirmation message
page=container['thanks.html']
return page()
