[Dovecot] Mail deduplication

[Tim Groeneveld]

Hi Guys,

I am wondering about mail deduplication. I am looking into the possibility
of seperating out all of the message bodies with multiple parts inside mail
that is recived from `dovecot` and hashing them all.

The idea is that by hashing all of the parts inside the email, I will be
able to ensure that each part of the email will only be saved once.

This means that attachments & common parts of the body will only be
saved once inside the storage.

How achievable would this be with the current state of dovecot? Would it
even be worth doing?

Thanks,
    Tim
