[exim] File Access Error - Stumped

Trying to figure out what's causung this error:

2006-04-02 19:16:14 1FQEc2-0008MU-AJ == marc@??? R=virtual_userforward defer (-1): bad mode (0100777) for
/etc/exim/control/domains/perkel.com/users/marc/filter.txt: 022 bit(s) unexpected

Here's the router that's causing it. Thanks in advance.
