mainly because my clients want to receive mail from that domain,
and anyway i do not want to temporary reject any mail because a
hostname that may or may not exist produces a dns defer, specially
when the acl check is just for informational purposes and i
specifically instruct exim to ignore unknown hosts.

In the other hand the reason why i accept or reject a message is
my decision, not of interest of this list (i supose) and does not
affect in any way the real solution to my problem.

The question is, why does not work +ignore_unknown ? why does it
make the whole condition to defer where it cannot find the
ip address of a host ?
