According to Python documentation[1], email.policy is new in version
3.3. Isn't fair enough have compatibility with Python 3.3+?

The documentation indicates that what have changed in 3.6 is the
"default" message factory[2]. That seems not being touched by your
patch.

Travis disagrees though: :(

  File "/home/travis/build/patchew-project/patchew/tests/test_tags.py",
line 58, in test_mbox_with_8bit_tags
    parser = email.parser.BytesParser(policy=email.policy.SMTP)
AttributeError: module 'email' has no attribute 'policy'

on all of 3.3, 3.4 and 3.5.

So we need some help from Travis folks. I've built a fresh Python 3.3.7
on my machine and the policy module is there. 

➜  bin git:(master) ./python
Python 3.3.7 (default, Nov 27 2018, 15:10:34)
[GCC 8.2.1 20181105 (Red Hat 8.2.1-5)] on linux
Type "help", "copyright", "credits" or "license" for more information.
... from email import policy
... dir(policy)
['Compat32', 'EmailPolicy', 'HTTP', 'HeaderRegistry', 'Policy', 'SMTP',
'__all__', '__builtins__', '__cached__', '__doc__', '__file__',
'__initializing__', '__loader__', '__name__', '__package__',
'_extend_docstrings', '_has_surrogates', 'compat32', 'default',
'strict']
...

Should we open a ticket? I did a quick search and couldn't find
anything related with that. It's pretty specific.

I found it, on older Python you must explicitly import email.parser and
email.policy.
