[Exim] error writing to inbox

Hi,

I'm getting this error in my /var/log/exim_mainlog

2002-12-19 11:36:54 18P3fK-0006mZ-00 == webmaster@???
T=virtual_sa_userdelivery defer (-25): filter process failure 2 while
writing to /home/myusername/mail/mydomain.com/webmaster/inbox

Here is the transport its using:

virtual_sa_userdelivery:
driver = appendfile
file =
"${extract{5}{:}{${lookup{${lookup{$domain}lsearch*{/etc/userdomains}{$value}}}lsearch{/etc/passwd}{$value}}}}/mail/${domain}/${local_part}/inbox"
quota = "${if
exists{${extract{5}{:}{${lookup{${lookup{$domain}lsearch*{/etc/userdomains}{$value}}}lsearch{/etc/passwd}{$value}}}}/etc/${domain}/quota}
{${lookup{$local_part}lsea
delivery_date_add
envelope_to_add
return_path_add
user = "${lookup{$domain}lsearch* {/etc/userdomains}{$value}}"
group = mail
transport_filter = "/usr/local/bin/bogofilter -d /root/.bogofilter -e
-p -l -u"
mode = 0660



The exact same transport worked before, just using "/usr/bin/spamc" as
the transport_filter. I wanted to try & pipe through bogofilter instead
of spam-assassin, for giggles.

Thanks for any help,
Brandon
