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

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@mail.com' sender='fromMe@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()
