-The life cycle of a LEAP Email
-==============================
-The following are just some notes to facilitate the understanding of the
-leap.mail internals to developers and collaborators.
-
-Server-side: receiving mail from the outside world
---------------------------------------------------
-
-1. the mx server receives an email, it gets through all the postfix validation and it's written into disk
-2. ``leap_mx`` gets that write in disk notification and encrypts the incoming mail to its intended recipient's pubkey
-3. that encrypted blob gets written into couchdb in a way soledad will catch it in the next sync
-
-
-Client-side: fetching and processing incoming email
----------------------------------------------------
-you have an imap and an smtp local server. For IMAP:
-
-1. soledad syncs
-2. **fetch** module sees if there's new encrypted mail for the current user from leap_mx
-3. if there is, the mail is decrypted using the user private key, and splitted
- into several parts according to the internal mail data model (separating
- mutable and inmutable email parts). Those documents it encrypts it properly
- like other soledad documents and deletes the pubkey encrypted doc
-4. desktop client is notified that there are N new mails
-5. when a MUA connects to the **imap** local server, the different documents are glued
- together and presented as response to the different imap commands.
-
-
-Client side: sending email
---------------------------
-
-1. you write an email to a recipient and hit send
-2. the **smtp** local server gets that mail, it checks from whom it is and to whom it is for
-3. it signs the mail with the ``From:``'s privkey
-4. it retrieves ``To:``'s pubkey with the keymanager and if it finds it encrypts the mail to him/her
-5. if it didn't find it and you don't have your client configured to "always encrypt", it goes out with just the signature
-6. else, it fails out complaining about this conflict
-7. that mail gets relayed to the provider's **smtp** server
