Message Delay
Hi all,
When I sent out mass external email I receive this message,
========================== ========
Subject: Delivery Status Notification (Delay)
This is an automatically generated Delivery Status Notification.
THIS IS A WARNING MESSAGE ONLY.
YOU DO NOT NEED TO RESEND YOUR MESSAGE.
Delivery to the following recipients has been delayed.
recipients email addressess
========================== ========== ====
And alot of my recipients tell me that they got multiple duplicate emails from me.
Can someone tell me what causes that delay and how can I fix it?
I am currently on Exchange 2003.
Thanks,
James~

Because you sent a lot of e-mails your queue has blocked (slowed) somehow (maybe from the antivirus, maybe because the hardware system is to slow). Try to check the queue, restart the services and look for errors in the Event log.
There could be lots of reasons for the delay messages.
By mass email, what are you talking about? 10, 100, 1000 more?
Internal or external users?
What else is on the machine, and how fast is your connection to the internet. In this respect the UPLOAD speed is more important.

About 300+ mail
What size are the messages?
You could be simply experiencing delays caused by internet connection or throttling from your ISP. Exchange doesn't do bulk emailing very well. If it is going to be something done regularly then you should look at something designed for the job.

Sorry, been out of the office for awhile didn't mean to leave it open like that.
Anyways, I found this error in my event view. Event Type: Error

Event ID: 2013

Time: 12:03:23 AM
User: N/A

Description:
SMTP could not connect to any DNS server. Either none are configured, or all are down.
Could this be the cause of it?

That certainly would cause some problems.
How is your DNS configured?
Make sure that you have not got any DNS servers configured in Exchange itself.
Ensure that the only DNS servers in the network configuration is for the domain controllers ONLY. No external DNS servers should be listed anywhere.
If you need to use external DNS servers for effective name resolution, then use forwarders on the domain controllers.

Yes, this exchange server is also a DNS server. Is that going to post a problem?

Yes, the Exchange server is a domain controller as well.
How can I tell rather the server is using an external DNS servers or not?
Thanks,

In your network configuration make sure that you only have the domain controller itself as primary and the other domain controller as secondary. There should be no external DNS servers at all anywhere in the network configuration.
If the server is dual homed, then remove the DNS servers totally from the internet facing NIC, so that the only DNS servers are the ones on the internal NIC.
