I've uploaded a mutt-kz package to the Arch AUR that is includes patches for neat
stuff like conditional dates and nested if statements.
I use this, for example, to format my dates as "Today" and "Yesterday"
or "May 12" depending on age. See
https://picasaweb.google.com/112461840507804909912/Screenshots#5834857965... for an
example. The muttrc (work in progress) I'm using for mutt-kz-dgc-git use is here:

The AUR page is:
