I'm not sure what you mean by "orphaned" in that context. Are the mailboxes for domains which you host, or for other domains? > I've started by configuring the front end server to check local_part against > a list for the domain. relay_to_domains used to be configured to do lsearch > to check the domain so I've changed exim.conf to use dsearch: > > domainlist relay_to_domains = dsearch;/etc/exim/relay > > and I've modified the manualroute router to use dsearch and to check the > local_parts too: > > backendrouter: > driver = manualroute > domains = dsearch;/etc/exim/relay > local_parts = lsearch;/etc/exim/relay/$domain > transport = remote_smtp > route_list = * backend.server.tld > > To stop the frontend server from accepting messages for relay where the > local_part isn't defined in /etc/exim/relay/domain do I need to configure a > dsearch in acl_check_rcpt check too? If so, how? And you're manually maintaining the contents of the /etc/exim/relay/$domain files, presumably. All looks sensible. Basically what you need to do is: 1. Ensure that good addresses are routable, and that bad addresses are not. Use "exim -bt" (on the front end server) to test this. You probably want to test at least four types of addresses: * [EMAIL PROTECTED] * [EMAIL PROTECTED] * any address at a known, external domain (e.g. [email protected]) * any address at a non-existent domain (e.g. [EMAIL PROTECTED]) 2. Make sure your acl_smtp_rcpt includes "require verify = recipient" somewhere. -- Dave Evans Power Internet Limited, registered in England #03053650 at Norfolk House, 82 Saxon Gate West, Central Milton Keynes, Buckinghamshire, MK9 2DL.
