Author: Mike Brudenell Date: To: exim-users Subject: [exim] Help: manualroute router and ignore_target_hosts?
Greetings -
Could someone help shed light on what the problem is with the following?
I have just noticed that out Authenticated SMTP server (running Exim
4.63) is accepting messages destined for recipients whose domain name
is an MX pointing at local or loopback addresses: eg, at 127.0.0.1
Our Authenticated SMTP servers merely accept mail and pass everything
on to the main mail gateways, so I use the manualroute router to do
this. Rather than accepting e-mail to such problematic recipients
only to then have it refused by the main gateways (currently still
running Sendmail) I'd like to ignore/drop them at the A-SMTP server.
I have found the ignore_target_hosts option and read in the
manualroute router section (20.2) of the Exim 4.63 Specification:
> The generic ignore_target_hosts option applies to all hosts in the
> list, whether obtained from an MX
> lookup or not.
This implies/confirms that the generic ignore_target_hosts option
should work with the manualroute router.
However trying this shows it doesn't seem to work: I tried sending a
test message to one such problematic e-mail address, expecting Exim
to reject it as unrouteable. Instead it was accepted by the
send_to_smart_host router (see below) and transmitted to the main
mail gateways, only to then get it rejected (subsequently depositing
it in my Postmaster mailbox! :-(
Can anyone tell me where I'm going wrong, please? Here is the
section from the configuration file:
=============================================
begin routers
# This router routes all non-local addresses to a central smart host.
