I've hit a wall with mailman which seems to be caused by pyhon's character
encoding names.
I've narrowed the problem down to the email/charset.py file. Basically the
following happens:
given an encoding name as 'iso-8859-X' it is transformed to 'iso8859-X'
(without the first dash). This happens with python 2.7, but not with python
3.4. Now Microsoft Exchange doesn't like the form without the dash, and
bounces the emails from Mailman. And Mailman doesn't work with python 3.x.
This transformation is done in charset.py with the following line
input_charset = codecs.lookup(input_charset).name
The following code example demonstrates the issue
from email.charset import Charset
charset = Charset('iso-8859-7')
print(str(charset))
In python 2.7, iso8859-7 is printed. In python 3.4 iso-8859-7 is printed.
I tried to find the location of these mappings in the codecs.py file, but
it seems that it uses some internal mapping I couldn't find. And I'm not
100% sure that this is not OS related.
So the question basically is if there is a way to change the name mappings
this codecs file does.
My environment is Ubuntu 14.04
python2.7 --version
Python 2.7.6
python3.4 --version
Python 3.4.0
