>Description:
Terminfo include a definition for rxvt-256colors, but termcap does not.  This prevents zsh and mutt (and probably others) from using that terminal definition.  These utilities complain when TERM is set to rxvt-256colors, even though they apparently use terminfo instead of termcap.
>How-To-Repeat:
In zsh,

export TERM=rxvt-256colors

(reproduced if zsh complains that it can't find the terminal definition.

Now start mutt -- reproduced if it will not start, complaining about the missing terminal definition.
>Fix:
I added the following to /etc/termcap to fix the symptoms:

rxvt-256color|rxvt terminal emulator with 256 colors:\
        :Co#256:AF=\E[38;5;%dm:AB=\E[48;5;%dm:tc=rxvt:
