# This autoloadable function checks the folders specified as arguments
# for new mails. The arguments are interpeted in exactly the same way
# as the mailpath special zsh parameter (see zshparam(1)).
#
# If no arguments are given mailpath is used. If mailpath is empty, $MAIL
# is used and if that is also empty, /var/spool/mail/$LOGNAME is used.
# This function requires zsh-3.0.1 or newer.
#
