- Where would I add this to named.conf?

- If I place the ISP's NS before the local NS (192.168.3.X) I receive
transient parse errors when attempting to send msgs from the mail server.
It is also VERY slow when I do that (I tried that on 14JAN05).

Hence, the quotes around the word right...  :)




It appears this entire ordeal could be caused by a message being "stuck" in
one of the five queues used by the JavaMail API in their Java app.  They
restarted their app just a bit ago and three of the five queues cleared out
in seconds while the other two just sat there for some reason.  To be quite
honest, I hope this is the case!!!

Thank you for all of your help (this is to everyone who responded btw).  If
I am still experiencing difficulty with this later today I will be back...
