====== Maildir ======
The maildir standard mailbox format is described in ''maildir(5)''.
* Each maildir contains a set of subdirectories: //cur//, //new// and //tmp//.
* Enhanced maildirs support subfoldering through contained maildirs whose name starts with a dot (e.g. //maildir/.sub/{cur,new,tmp}//).
* Many IMAP implementations are maildir compatible.
===== Subfolder =====
* Each subfolder name by convention has a leading dot (''.'').
* The internal structure of a subfolder is exactly the same as a regular maildir, i.e. the three subdirectories //cur//, //new// and //tmp// must exist.
**Subfolders of a subfolder don't reside in the subfolder!** I.e. the hierarchy
ends on the subfolder level, all consecutive subfolders are constructed by
using special names. See the following example:
$HOME/Maildir/cur
$HOME/Maildir/new
$HOME/Maildir/tmp
$HOME/Maildir/.Folder
$HOME/Maildir/.Folder/cur
$HOME/Maildir/.Folder/new
$HOME/Maildir/.Folder/tmp
$HOME/Maildir/.Folder.Sub
$HOME/Maildir/.Folder.Sub/cur
$HOME/Maildir/.Folder.Sub/new
$HOME/Maildir/.Folder.Sub/tmp
Here ''Sub'' is a subfolder of the subfolder ''Folder''.
