I do this kind of thing in several Handlers.  There are two ways to
approach this.  The easy way is that the Handler knows what list it is
processing (the mlist argument to process()):

    if mlist.internal_name() in my_lists:
        # do my thing

The more elegant way (and not much harder) is to define a
MyVeryOwnSpamDetect handler (which starts as a copy of
SpamDetect.py!), save it to the Handlers directory, then insert it in
the list's configuration with

$ cd /path/to/mailman/lib; bin/withlist -l mylist
> mlist.pipeline = GLOBAL_PIPELINE
> mlist.pipeline[position_of_SpamDetect] = 'MyVeryOwnSpamDetect'
> mlist.Save()
> <Ctrl-D>
$

And now you know why all the cool kids love Mailman!
