Hello to all:
We have a problem about MX name resolution in exim. We don't want our
server to resolve the address in the following router:
The router
router_ldap:
driver = lookuphost
ignore_target_hosts = 127.0.0.0/8
transport = smtp_backend
condition = "${lookup ldap
{ldap:///LDAP_BASE?LDAP_ATTRIBUTES?sub?LDAP_FILTER1}{true} fail}"
headers_add = Mailhost: ${extract {mailhost}{${lookup ldap
{ldap:///LDAP_BASE?LDAP_ATTRIBUTES?sub?LDAP_FILTER1}{$value}}}}
domains = /opt/exim/etc/domains
We have two conditions that have been met, so we can't figure out how
exim is resolving names in this stage of processing: (look at the log):
router_ldap router called for pozi@???
dns lookup: route_domain = myexampledomain.com
DNS lookup of myexampledomain.com (MX) gave HOST_NOT_FOUND
returning DNS_NOMATCH
DNS lookup of myexampledomain.com (A) gave HOST_NOT_FOUND
returning DNS_NOMATCH
router_ldap router declined
The transport smtp_backend use gethostbyname, so we don't want
router_ldap to do the resolution, but smtp_backend.
Here's the transport:
smtp_backend:
driver=smtp
max_rcpt = 1
gethostbyname = true
delay_after_cutoff = false
hosts_override = true
headers_remove=Mailhost:Bcc
# we get the host from a ldap lookup
hosts = ${extract {mailhost}{${lookup ldap
{ldap:///LDAP_BASE?LDAP_ATTRIBUTES?sub?LDAP_FILTER1}{$value}}}}
Any idea ?
