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?
I asked the same question recently. As Timo responsed at
http://kevat.dovecot.org/list/dovecot/2013-March/089072.html it seems
that this feature is production stable in recent versions of dovecot.
And I think it is worth. My estimations (with just about 10 users of my
organization, they are no accurate) is that you can save more than 30%
of total mail storage.
To configure it you need to use options:
* mail_attachment_dir
* mail_attachement_min_size
* mail_attachment_fs
* mail_attachment_hash
