[Zope] How to create a file and send it by e-mail ?

Hello all, I'm developing using ZPT and I need to create a file (CSV format) but I'm having some problems: * 1. *I only know how to create files with python but I get an * Error Type: NameError* * Error Value: global name 'file' is not defined. * I think ZOPE doe's not allow python to create files for security reasons. Can I change this security policy or it will make my application unsafe? Is there another way to create a file using ZOPE API calls ? * 2.*When I create my file how can I send it as an attachment by mail ? (I already have setup my mail host object and I can send mail's successfully.) thanks for your time.. * *
