<br>
Ya...definitely a DNS issue. I think the problem is on my internal mail<br>
server for some reason.<br>
<br>
Don't have a caching name server setup because I felt that the amount of<br>
traffic we were generating did not warrant a caching name server. So the<br>
mail gateway is just using our ISP's DNS server for queries.<br>
<br>
Internal, I setup a private BIND server that serves up private hosts as<br>
well as act as caching name server.<br>
<br>
What I noticed just now is that I sent a test email to myself (so it would<br>
just go through the mail server) and it appeared to take a long time for
my<br>
mail client to connect and send the message....<br>
<br>
Any recommendations?<br>

<br><font size=2 face="sans-serif">Make sure your private BIND server is
running and giving reasonable answers, and that the servers it</font>

it. </font>
