It could just be the documentation, but it looks like the attribute
binding may not work at the class level. Wrap your styling info in a
STYLE and see if that works.

CLASS
NAME 'crews'
# MAXSCALE 250000
STYLE
COLOR [symcolor]
BACKGROUNDCOLOR 255 255 255
OUTLINECOLOR 255 255 255
SYMBOL 'crewsymbol'
SIZE 25
END # end of style
LABEL
COLOR [symcolor]
OUTLINECOLOR 255 255 255
TYPE TRUETYPE
FONT arial
SIZE 9
MAXSIZE 9
MINSIZE 8
ANTIALIAS TRUE
POSITION UC
PARTIALS FALSE
FORCE TRUE
END
END
