I think I see a problem with my lookuphost router. Can anyone
help?
Problem is this:
Machine running Exim 2.10 under Solaris 2.6 is a mailhub, routing
mail to a number of remote subdomains of le.ac.uk, eg.
rose.le.ac.uk. Such addresses are handled by the lookuphost router,
the config file definition of which is as follows:
deliver:
driver = lookuphost
widen_domains = le.ac.uk:leicester.ac.uk:ac.uk
self = fail_hard
transport = smtp
I see a problem when routing mail for one of our subdomains when
it is unqualified, eg. user@rose
In this case, I would expect the DNS lookup to be for the domain
rose.le.ac.uk, since qualify_single defaults to TRUE and
primary_hostname is artemis.le.ac.uk
However, as the following debug output shows, the lookup is
done on domain rose, not rose.le.ac.uk
> exim -d9 -bt user@rose
Exim version 2.05 debug level 9 uid=1001 gid=10
probably ndbm
Address testing: uid=0 gid=10 euid=1001 egid=10

router = deliver, transport = smtp
host rose.le.ac.uk [143.210.22.23]
search_tidyup called
We also have a subdomain of the form a.b, and I tried setting
search_parents = TRUE, but found that the lookup was done for
a.b rather than a.b.le.ac.uk
Is this a problem with Exim, or with my understanding? I suspect
the latter, since I cannot find any mention of such a bug in the
list archives.
Thanks in advance for any help.
