External directory folders

[Uday Reddy]

John Hein asks (viewmail-info, 2012-01-18):

I like [the fairly recent] headers only mode for imap folders.

What about for local folders? That would help for some of my larger
local folders, especially for load/save operation times (especially
over nfs) and searching based on header contents (rather than body
searches).

This might help mitigate some (not all) of the reason I'd like to see
maildir support in vm. Although I'm not sure which would be easier
to implement.

I have been thinking about that recently. The first thing to do would be to
allow a directory of (single message) mail files to be viewed as a folder.
I will call them "directory folders" for the time being.

The first time you load a directory folder it would be time-consuming
because a directory is not a mail server and you can't ask it to give you
just the message headers. But, once the folder has been craeted, viewing
messages should be fairly efficient.

But 107092 gives background on maildir support.
