'lambda' and 'folder' are inverted.  Why the space before the backslash?
Why the inner parenthesis?

folderfilter = lambda f: not re.search ('INBOX\.', f)

Checking your rules in your python shell:

# python2
>>> import re
>>> a = lambda f: not re.search ('INBOX\.', f)
>>> a('.INBOX.Trash')
False
>>> a('.Trash')
True
>>>

When True, the folder is synced.

You need nametrans and reversed nametrans (in the remote and local
sections).

remote nametrans:
nametrans = lambda f: '.Sent' if f == '.&AMk-l&AOk-ments envoy&AOk-s'

local reversed nametrans:
nametrans = lambda f: '.&AMk-l&AOk-ments envoy&AOk-s' if f == '.Sent'
