[Dovecot] Mail deduplication

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
