Hi !!
I have a problem where a domain has some dns problems and it's
on a host list like this:
hosts = +ignore_unknown : *.$sender_address_domain :\
$sender_address_domain : ${lookup dnsdb{>:\
defer_never,mxh=$sender_address_domain}}
looks like some problem trying to resolve the hostname cioce.com
causes the whole acl check to defer with a 451 Temporary local problem
I suposed that the +ignore_unknown option will also make any lookup
defer to ignore the list item and proceed with the following one,
but the only way to avoid temporary reject that message forever is
to put that domain in dns_again_means_nonexist (which i don't like).
Maybe it will be better if +ignore_unknown could handle that situation
nicely.
debug output follows:
>>> check hosts = +ignore_unknown : *.$sender_address_domain
:$sender_address_domain : ${lookup dnsdb{>:
defer_never,mxh=$sender_address_domain}}
>>> cioce.com in dns_again_means_nonexist? no (option unset)
>>> no IP address found for host cioce.com (during SMTP connection from
smtp.telefonica.net (ctsmtpout3.frontal.correo) [213.4.149.66])
>>> host in "+ignore_unknown : *.cioce.com :cioce.com : "? lookup
deferred for cioce.com
>>> accept: condition test deferred
>>> deny: condition test deferred
>>> drop: condition test deferred
451 Temporary local problem - please try later
