I would set it to 250 if your isp will take it. 15 is definitely too low.

How many email addresses in the list.

Thanks for the reply.

Currently my DNS Timeout is set to 25 seconds. I also have 15 concurrent requests and a retry limit of 5. Should I maybe move the concurrent requests up to 50 just to see how it goes?

I have listed my ISP's DNS server, then my AD server's IP, and then my ISP's second DNS server and set the DNS Server Address to Custom. It doesn't seem like the mail server is moving to the next DNS Server if there's an error, or a delay. Isn't that how it's supposed to act?

No the issue appears to be with your dns servers. I have seen this with
in
the past when the dns server get overloaded with request and cannot
respond
in time. You may want to check you initial dns time out under the
obscure
settings. Increase the time out to maybe 7 seconds.

I seem to remember someone in the past with the same issue and they had
a 1
second timeout.

Subject: Mailing list warning messages


Hey,

I wanted to see if we could revisit this subject again. I'm still
having
annoying DNS Server Failed errors on my outbound mail queue. It seems
like
any messages containing more than a couple recipients get caught up in
the
Queue for no apparent reason. This happens the most with our mailing
lists.

I'm getting strange DNS failures but then when I go into the Monitors /
Mail
and click on the messages and release the queue it sends. This is
obviously
very annoying to the mailing list recipients as they continually get
WARNING
messages for no reason.

09:52:24.269 3 DNR-025994(wfla.com) MX:DNS server failure
09:52:24.269 3 DNR-025995(bradentonherald.com) MX:DNS server failure
09:52:24.269 3 DNR-025991(yourobserver.com) MX:DNS server failure

But if I go and do a nslookup for those domains' MX records, they
resolve
just fine. If I do nothing I've seen messages sit in the Queue for 3
days
without being sent. Is there some setting in the bowels of the CGPro
Administrative interface that might be holding these messages up?

Help??

Good suggestion! I'll give that a try. I'd been using my AD server but
things seem to get a little bound up at times on that due to heavy
loads...
that's why I changed over to the ISP servers.

Thanks!

I have bonded T1's here also. But I run my own DNS servers and don't
rely on
a upstream ISP for dns. Another possiblity could also be overloaded DNS
servers at your ISP and you have no control over that. It's not hard to
setup recursive dns service on a *nix box to bypass your upstream
providers
servers and provide yourself with another layer of redundancy and
caching.

That could be. I have a 3 meg pipe to the Internet though. The only
error
messages I'm seeing are:

11:21:12.032 3 DNR-001084(netzero.net) MX:DNS server failure
11:19:18.030 3 DNR-001003(wfla.com) A:DNS server failure

But there's no reason associated with it. Just that it failed.

Some info about my network: I am multi-homed and I have set things up
so all
DNS requests from my network go out my bonded T1's. So I'm using that
ISP's
DNS servers primarily.

Thanks for the help!

Have you looked at congestion on your Internet connection? It's
possible
that you are flooding(too many simultaneous outgoing SMTP channels??)
your connection and the UDP packets from the resolver are getting lost.
Are you getting DNS error messages in CGPro's logs when the list is
sending out?

I constantly get warning messages that stack up in my queue from our

PR guy's mailing lists he sends to. It seems like every e-mail he has
in the list gets a DNS failure at first and generates this bounce
message:

This is an automated message from the mailing list...

List messages sent to your address <e-mail > have bounced.

If you read this message, your mail system has been probably fixed.

To clear the bounce counter and to prevent automatic cancellation of
your subscription, use the Reply command in your mailer.

Check that the Subject of the reply message contains
the confirmation ID: 0621242263,
and the reply is directed to <list@domain.com>,
and the 'From' address of your reply is <email>.

All requests about this mailing list
should be sent to <list@domain.com>

But when I do an nslookup on the domain the person is from, it

resolves fine. And generally if I go into the queue and click Release
Now, it sends the message fine. The problem reported is DNS server
Failure. It's getting pretty annoying. Is there a setting I'm missing
that either will help the bounces stop happening (this particular e-
mail address was a hotmail.com address) or not send a warning after
just one delay or DNS failure? I've tried all sorts of DNS servers,
including 4.2.2.2 but these failures continue.

Thanks for the help!
