'xterm -e mutt' doesn't show colors

[Pieter Verberne]

Hi,

When I run mutt (or tmux/colorls -G/etc) from xterm, I have fancy
colors=] But when I run:

$ xterm -e mutt

I don't have colors =[ (I'm running dwm and I want xterm to start tmux
automaticly)

$ cat .Xdefaults
     XTerm.*.colorMode: on      # yes, two capitals
     XTerm.*.dynamicColors: on
     xterm.*.loginShell: true
     xterm.*.scrollBar: false
     xterm.*faceName: Mono
     xterm.*faceSize: 13
     xterm.*.visualBell: true

$ echo $TERM
xterm-xfree86

All other settings in .Xdefaults are applied just fine with the '-e'
option, so I don't think it's a problem with that file or with
xterm-options; -title -T or -n .

Can someone help me with this puzzle?

Pieter
