[SM-DEVEL] Support for more flags

[Pander <pa...@us...>]

Hi all,

At the moment Squirrelmail 1.4.22 and the development version supports the
flagged flag by either giving the email entry in the overview pane a red
font or providing it with a red flag.

This flag can also be toggled via Thunderbird by pressing '1' when that
particular message is selected. By default Thunderbird offers five
different flags, see

Could SquirelMail also support the four additional flags please?

Implementing this will improve using flags among different kind of email
applications. A similar request is also pending at K-9 email client for
Android.

Regards,

Pander
