True, minimum cache timeout is one minute, so one will have bear that obviously huge overhead of at least 60 seconds.

I guess if someone wants to have their mail client download headers for all mails every time they click on an IMAP folder they will find an alternative mail client that never ever accesses local storage.

But such a person would have not used KMail at any prior version anyway, because it also did cache headers.

or they will use a smarter IMAP client that doesn't have to download all headers every time you open a folder. from your comment this means not using kmail (I haven't used it so I can't say

When the user tells an IMAP client to open a folder, it basically has three options:

(1) show no content
(2) download headers and populate folder with the recevied data
(3) use cached data to populate folder

Now you have made it abundently clear that you don't want option (3), you seem to be somewhat opposed to option (2) so that leaves option (1).

A valid choice, though I am not sure how many others would use a term like "smarter" to describe such behavior.

KMail (with or without Akonadi) uses option (3), based on the assumption that its target users prefer folders to be populated automatically upon open and prefer not to download headers every single time.

it doesn't need to download all header information, it only needs to download the information needed to display the screen

so not all information and not all headers.

it normally needs to download sender, date received, message size and subject for somewhere between 30 and 60 messages.

this is a far cry from downloading all header information for a folder with 10's of thousands of messages in it.

this does assume that you are using a decent IMAP mail server that can support things like server-side sorts, etc.
