Comment 8 for bug 266375

Originator: NO

You can disable header wrapping in the module (if I am looking at the
correct Python docs) according to this page:

http://docs.python.org/lib/module-email.generator.html

It implies that by passing through maxheaderlen set to 0 to all calls of
Generator then you shouldn't get this wrapping behaviour, though I don't
know when this appeared in Python.

I believe this may also be the the cause of Mailman breaking my PGP/MIME
messages as diff'ing the saved original and the version that comes back
shows that the only differences are for long MIME headers and for
reformatting of the headers in the message/rfc822 attached email.

I am not sure if this is related to 815297, but it sure looks like it.

Caveat: I am not a Python programmer, just a Postmaster..
