I'm having CNAME issues when trying to deliver outbound mail. Almost
all the mai is getting held up going outbound by an error saying
CNAME_lookup_failed_temporarily._(#4.4.3).
I've looked all around and find that all the solutions related to an old
patch which is in this version of code.
I also noticed that the system spends quite some time trying to deliver
these messaged before the failure.
It used to work fine, but here are the two things that changed:
1) Moved it into production and changed the hostname.
2) Put it behind a Cicso PIX that is running intrusion detection.
The PIX keeps raising intrusion alerts on the qmail server relating to DNS.
Sounds like PIX is blocking dns queries, fix it.
