[Bug 1290413] [NEW] postfix-to-mailman.py does not recognize lists that end in a control extension

[Helge]

Public bug reported:

Ubuntu 10.04.4
Version: 1:2.1.13-1ubuntu0.2

The postfix-to-mailman.py script does not recognize list names like
"mylist-admin" or "mylist-request".

Currently it strips off the control extension (e.g. "-admin", "-owner",
etc.) from mlist before checking if it actually exists.

This patch is very simple:
- Before checking for control extension, check if list_exists(mlist)
- Import list_exists from Mailman.Utils a little earlier.

Before applying this patch, trying to post to "mylist-admin" would
result in bounce message: "user unknown"

** Affects: mailman (Ubuntu)
