Dear Mike,

Thank you for an instant answer.

|Upgrade. BIND 8.1.2 has several root exploits.
|

Yes. Although I think that we also want to carry out early, 
there is no opportunity which can stop what is moving very much,
 and I am troubled. I will make URL you teach me reference.

|There is no "dom" TLD. According to dig:

I am sorry that explanation is insufficient...
The domain of this problem is our customer's domain, and the 
name is hidden. I am sorry.
"domain.dom" is a fictitious domain. Theres no TLD named "dom".

Although names differ, the composition of a customer's domain
is this passage.

# It understands. I want to make it clear, but I cannot.
# I know that impossible wish..

What does it generally opinion-get in a thing with appropriate 
thinking in the case of such sendmail log?
