918200 - [email] POP3 support: Implement header-only and/or snippet fetching

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Gaia::E-Mail, defect)

Description

[Andrew Sutherland [:asuth] (he/him)]

Implement the back-end support so that POP3 initially synchronizes only the envelope of a message, then later can go back to fetch the snippets, then finally, when requested, the body.

This is a refinement of the whole-body fetching which we first plan to implement.

Besides the downloading bits, which we do not expect to be particularly complex, the other key bits are:

- Heuristic for deciding whether there's an attachment or not.  We're mainly thinking check for the existence of multipart/mixed at the outer header level without evidence showing there are no attachments, as well as just guessing based on message size.  Huge messages will tend to have attachments.

- Making sure the mailparser handles an EOF occurring during a message body.  It probably already handles this, though there might be some edge cases, etc.
