Timeout problems

[Eric]

There is nothing relevant in /var/log/messages, definitely no errors.
Don't have the other logs mentioned.

I included an excerpt previously of what was happening in maillog:

Doing some more research, perhaps my local DNS cache was not setup properly.

/etc/resolve.conf was missing the following line:
nameserver 127.0.0.1

Only had references to my actual name servers. BIND is running. Did some
dig queries, and looks like the cache is working. First query will take
100-200ms or less. Second query 1ms or 2ms, indicating cache.

I will just wait and see if the errors show up again. Quite random. Once
in three months, then once per week, and then daily. Is there anyway to
test and force the error?

However, would the DNS be the culprit? I don't have a high load, only
800 messages per day.
