I've created a directory where I can add all the files to generate (or
edit) the signature from the dkim library.

This probably requires some refactoring of dkimpy.  It might also

Yes, some minor changes will be required I believe, like changing the
default frozen headers to be signed or the tags to be added in the sign.
Still, some of them can be circumvented by editing the generated signature
in a separate file.
And yes, I'll go through the other packages you suggested before to see if
I am able to read them better than dkimpy.

And yes, I've just pushed the files to github as of now, so that I am able
to get your insight in the proceedings. I'll start working in gitlab soon
once I'm able to come up with a sketch of things.

Thanks!
