STMP server smtp.xyz.com. needs to send a message to some...@xyz.com. An MX
lookup is performed for domain xyz.com. and the domain name of mx.xyz.com is
returned. This is the first sentence:
When a

I do receive both the CNAME and A records for the A mx.xyz.com query. See
attached capture file.
In the capture file three global search and replacements were performed to
match the previous example.
1) domain name was replaced with xyz

No it is only two steps, see the attachment (sent in previous message).
Both the CNAME and A record are returned for the mx.xyz.com DNS A request.
And this does met the RFC requirements.

Hi,
I was going to upgrade from BIND 9.4.3 to BIND 9.6.0-P1, but run into a
strange bug in BIND 9.6.0-P1.
Exact same config for 9.4.3 and 9.6.0-P1, only added new to files that
are written to (namednew.log, confignew.log and namednew.pid).
