You could have procmail fire a python script to add or remove tags based
upon message content. 

Here's a python script I tried using to untag messages from the Lift
mailing list, there was a problem when I wrote it, but it's probably
been fixed by now.

#!/usr/bin/env python

from notmuch import *

'''
The idea of this script is that it will untag mailing list messages,
keeping them from my inbox unless they are directly related to me.

The problem is that the tag removal isn't being saved. 
I've created a bug report with the developer:

https://bitbucket.org/spaetz/cnotmuch/issue/1/removing-tags-doesnt-seem-to-be-saving

'''
db = Database('/home/bryan/.maildb',False, 'READ_WRITE')
q=db.create_query("'[lift]' -from:bryan tag:inbox")

for msg in q.search_messages():
    print msg.get_tags()
    msg.freeze()
    msg.remove_tag("inbox")
    print msg.get_tags()
    msg.remove_tag("unread")
    print msg.get_tags()
    msg.add_tag("lift")
    print msg.get_tags()
    msg.thaw()
exit()
