Support for "maildir"

[edi9999]

Currently, 3 methods are possible with meilindex : MBOX files, IMAP, mailspring.

I'm using offlineimap to sync the emails from my remote IMAP server to my local computer (http://www.offlineimap.org/).

From the docs of offlineimap :

OfflineIMAP is a GPLv2 software to dispose your mailbox(es) as a local Maildir(s). For example, this allows reading the mails while offline without the need for your mail reader (MUA) to support disconnected operations.

The directory structure looks like this :

├── INBOX
│   ├── cur
│   ├── new
│   └── tmp
├── INBOX.archive
│   ├── cur
│   │   ├── 1626735172_2.277897.host,U=3,FMD5=6ec33b7708e41596e6d4f5707101ac47:2,S

Since I myself don't know that much about mail storing possibilities, I can confirm that "maildir" is a specific mail storing system, one of the two most commonly used (mbox being the other one) : https://access.redhat.com/articles/6167512#:~:text=Two%20of%20the%20most%20common,in%20a%20simple%20directory%20structure.
