Seeing long delays with emails being delivered

[Alex Neuman]

Use IP addresses instead of dns names on your mail client, or check to see
if your private bind server is working.

Ya...definitely a DNS issue. I think the problem is on my internal mail
server for some reason.

Don't have a caching name server setup because I felt that the amount of
traffic we were generating did not warrant a caching name server. So the
mail gateway is just using our ISP's DNS server for queries.

Internal, I setup a private BIND server that serves up private hosts as
well as act as caching name server.

What I noticed just now is that I sent a test email to myself (so it would
just go through the mail server) and it appeared to take a long time for my
mail client to connect and send the message....

Any recommendations?

Thanks,

Jason
