    I missed this. It still defaults to True in Generator. It should default to False in the new policies (but True in compat32).

    Sorry, my message wasn't clear. The current default needs to remain the same. What needs to be added is email.policy.Policy.mange_from, which should be True in the compat32 policy and False in EmailPolicy. Then it needs to be hooked up the Generator, so that an explicit specificaion in the __init__ overrides the policy, but specifying one of EmailPolicy dervived policies will override the default value of the __init__ argument if the argument is not speicifed explicitly in the Generator constructor call. (Backward compatibility is a pain.)

    (@r.david.murray) I just implemented what you suggested:

    • Policy has a mangle_from_ property, overridden in EMailPolicy
    • Generator and DecodedGenerator default to policy.mangle_from_ or True if policy is None.

    Would be glad if it helps :)

    Added documentation for mangle_from. since the name "mangle_from_" is not supported by the markup, changed it to "mangle_from" everywhere, which looks better anyway (I understand why it was the other way so). If it was a bad idea, I can undo it but am unable to do the doc.

    Rollback to mangle_from_, sorry for the noise.
