[toaster] CNAME errors

[Rich Kasting]

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.

Any ideas?
