[exim] Central_filter_domain defer: failed to stat

Hi,

Last week due to a perl script deployed on my server, the parent folder of
my Central Filter got deleted. Due to this all mails defer and couldn't be
delivered. Is there any way using which mail bypasses the Central_Filter
Router in case it doesn't find the path to Filter file?

This is the Router:

central_filter:
    driver = redirect
    domains = +local_domains
    file = /central/filters/$local_part
    no_verify
    allow_filter
    allow_freeze

In my case the filters folder got deleted.


Thanks,
Gaurav Pruthi
