Sort by order received

[hippo]

Is it possible to make clicking on a columns header cycle through three stages? Some of the SPAM I get has fake date headers that result in them being displayed half way down my mailbox. I remember some mail readers having three sort orders:

• Date ascending
• Date descending
• Unsorted (but it's the order the messages are in the mailbox)

Failing that is it possible to add the IMAP server index as a column?

sort on arrival patch

I have made a patch to make this user-configurable, which you can of course make global by adding it to dont_override. Im hoping this can get added to core.

Personally I think this is a better way to deal with it than having 3 states in the sort column, from a server-side perspective. Sorting on date can have a serious impact on IO on the imap server, so it may be much better to sort on arrival (ie: unsorted). I think that if you allow for 3 states, most people will not choose the unsorted state. By making this a config setting instead most people wont change it. But i understand if people think differently and make this a 3 state column instead.

This patch is unfortunately not complete, i didnt think about database caching (which we dont use). So better not apply it.

I like the idea and also hate this spamming date trick. Corbosman, please do not abandon the patch.
