Describe the bug

• six have released version 1.14.0
• requirements.txt file has six fixed at v1.13.0 https://github.com/SpamScope/mail-parser/blob/develop/requirements.txt#L3
• This is giving dependency issues as some libraries download the latest, but this is fixed to 1.13.0
• We could bump it or change sign to >= ?

Expected behavior
Both Python Modules install fine

Actual behavior

Hi @sjcurtinibm,
this is a problem on your system and not of mail-parser. You should use virtualenv.
I can upgrade the library, but the best practice is the virtualenv.

@fedelemantuano six is updated often, and other packages have different version requirements. Setting a static version causes conflicts with setup.py requirements in other modules that use slightly newer or older versions of six, even if you use pip in a virtualenv. I agree with @sjcurtinibm , six should really be set at six>=1.12.0 to be more friendly to other dependencies in the same virtualenv.
