If the membership list needs to change on the fly, then use the new "virtual list" feature. I.e. create a list that all the message will appear to come from but build the recipient list on-the-fly. The easiest way to do this is, use a Python program to suck the data out of filePro (I've no idea how to do that), and build a Python list of recipients addresses. Then, make sure the installed Mailman package is in your sys.path (so your driver script can import Mailman modules).
Assuming you've got the listname, the list of recipients, and the message as plain text, it might be as simple as:
from Mailman.Post import inject
inject(listname, msgtext, recipients)Note that Mailman/Post.py can also be run as a command line script.
Alternatively, you might want to use the new extend.py interface to hook into the MailList instance for your list. If there's a file called extend.py in your lists/listname directory, it will be execfile()'d and a function extend() will be called, passing in the MailList instance.
Your extend() function can do something like, overload the Load() and Save() method so that membership data is funneled to your database. You probably just need to re-implement the MemberAdaptor.py interface and set the mlist._memberadaptor attribute to your customized version. Then everything else should Just Work.
If you're stuck on MM2.0.x, then you've got your work cut out for you <wink>.
