sorry to bother but what theheck does this mean.

The rewrite works (citec.net changed to mail-rbk.mtnns.net)
but it fails after that.

Any ideas?

>>> routed by dnslookup router


Shouldn't this go to my hub_route?

hub_route:
    driver = manualroute
    transport = remote_smtp
    domains = ! +local_domains :\
        lsearch;/usr/exim/virtual/virtual_domains
    route_data = lsearch;/etc/mail/exim-forwarders/1rewrite_rules
    host_find_failed = pass
    hosts_randomize



Regards, Tom

Depends on exactly what you mean by that.

(1) You can use .include in the config to include a separate file that
contains the rewrite rules.

(2) You can use lookups in a rewriting rule, for example

*@* ${lookup{$local_part@$domain}lsearch{/some/file}{$value}fail}

(3) Changing addresses while routing is usually done by the redirect
router, not by rewriting.

The standard Exim way of doing that would be to make the file contain
this:

booksite.co.za                 booksite.jev.co.za
dispatch.co.za                 mail.dispatch.co.za


and use a router like this:

redirect_domains:
driver = redirect
data = ${lookup{$domain}lsearch{/the/file}{$local_part@$value}}

If the lookup fails, the value of "data" is empty, which means that the
router declines. A setting of redirect_router would probably useful to
avoid multiple passes through this router.
