Try:

return template(self,content='hirst')

Right now, your DocumentTemplate has nowhere to get info_from_email *from*.

Also, btw, <!--#in "function()"--> is perfectly valid, I do it all the
time.  However, in a case where an ExternalMethod needs a 'self', you may
have to call it as:

<!--#in "function(name_of_folder_to_be_used_as_self)"-->

This was true in older versions of Zope, anyway, I don't know what the
current state of things is.
