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. send_to_smart_host: ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8 driver = manualroute route_list = !+local_domains mta.york.ac.uk transport = remote_smtp ============================================= Cheers, Mike Brudenell -- The Computing Service, University of York, Heslington, York Yo10 5DD, UK Tel:+44-1904-433811 FAX:+44-1904-433740 * Unsolicited commercial e-mail is NOT welcome at this e-mail address. * -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
