Hi Dylan,
If you know how to configure Postfix, you're 75% of the way there already. It's easy enough to whip up a Python glue script that can hit a URL, make a POST request or even script Zope directly. That's pretty much all that's required to bridge those two systems.
OK, I should write a script in Python for that. I think I can find info for the URL post, but I am lost when it comes to Zope; I don't know how to address Zope objects, their properties and methods from python, do you know of site for examples???
The tough part will be determining how to get your users to provide valid, parsable data by e-mail consistently enough to make it worth the trouble. The difficulty of this should not be underestimated. Normal people are very bad with structured data... computers aren't so great with unstructured data... it'll be a challenge to bridge this gap.
I am not worry about that, all I need is the e-mail address of the sender, a title from the e-mail subject, and a description, again from the body of the e-mail. Issues generated by e-mail would all end up having default "section", "type" and "urgency" values. Once in the system, a member of the support team (a notifyable in "Issue Tracker" lingo) will have to modify the issues attributes himself. Regards, Francois
