Temat: Re: [exim] Disable DNS checks in pipe delivery
Thank you very much Jasen, manualroute did the trick, I just had to
add the route_list clause to tell Exim to route all messages to the
pipe:

 everything_else:
    debug_print = "R: everything_else for $local_part@$domain"
    driver = manualroute
    domains = ! +local_domains
    transport = pipe_delivery
    same_domain_copy_routing = yes
    route_list = *
    no_more


Regards.
