Default configuration of fresh images makes partially downloaded e-mail unusable

[stippi]

When configuring a new IMAP e-mail account in the Mail settings, the "Partially download messages larger than" setting is enabled and the size is set to 0 bytes. This setting causes mails to be downloaded very quickly, as partial mails. Unfortunately, when opening the Tracker window for the mail box, it does not initialize with an attribute layout suitable for mails. Since there are no actual e-mail files contained in this folder (only partial e-mails that have a different MIME-type), one cannot configure the necessary attribute layout for e-mails. Partial e-mails apparently have only "thread" and "account" attributes defined for them. This makes it impossible to add the MAIL:when attribute column, which in turn makes the whole folder completely unusable, showing thousands of mails sorted by the time at which they were retrieved. The partial mail files do in fact have the correct attributes set on them, so it should be a matter of fixing the MIME-type at installation time. Even more convenient would be to automatically apply a suitable attribute layout to the Tracker window. Didn't R5 do something like that? Or was that only when searching for mails that the Query window had a special layout? Revision is hrev40697.

Hm I'm a bit lost where to add the extra attributes. I found a entry for normal mail in src/data/beos_mime/text/ but no entry for partial mails. Shouldn't there be one?

What are the mechanisms to create mime types? I don't understand how and where this two partial attributes are created!

By the way if you remove the partial mime type the mail daemon recreate the mime type correctly on the next start.

Thanks a lot, it works so good now, one doesn't need to download complete mails unless one is anticipating to be reading them off-line... :-).

Maybe I add an option to download the body of new, unread messages, think that would be handy.
