E2K Server Receiving NOT sending

No one can send email. After a long wait the user gets a message back with the subject:

Delivery Status Notification (Delay)
--------------------------------------------

I made sure SMTP was a running service. Also made sure the smtp virtual server was started.

I have seen many people get this same problem, but I can not find a solution.

OS-Win2K server
Software - Exchange 2k server

Is telus's smtp
        smtp.telus.net
             or
        smtp.telusplanet.net?

Thanks for the help

Who are you trying to send to?  Internal recipients on other Exchange servers?   The Internet?

How are you delivering from your Exchange server?  Did you setup an SMTP connector?  If so, are you using DNS or a smart host?  If you are using DNS, does it work?  

I'm not familiar with Telus.  I can tell you that the primary MX for telusplanet.net is smtp.telusplanet.net.  That is also the 3rd MX for telus.net.

there is multiple people users having this problem. It is using telus's smtp connector, Im not sure if I am using DNS or smart host. DNS probably. how would I check if it works?

Open Exchange System Manager.  Expand Administrative Groups, Routing Groups and Connectors.  Do you have an SMTP Connector configured there?  If not, you are using DNS.  If you do, you would specify a smart host on the General tab of the connector's properties.

Telnet to your telus server on port 25 to see if you can connect.  That is second thing you should do after finding out how you are delivering email (smart host or DNS).

Ok. Its smart host is smtp.telus.net, which I confirmed with telus.

It is saying that it is using virtual server. I checked the settings of this virtual server and all of the queues say they are ready, but there 413 messages unreachable destination folder. When I double click on any of these queues it has a folder icon with a red "!" in the corner. It says "enumerate messages from the queue node" in all of the folders.

Heres something.

One of queues is the SmallBusiness "SMTP connector (SMTP Connector - Remote Delivery)" switches between active and retry.

Commented:
Right, you have to enumerate the messages by right-clicking on the queue in order to see them.  Don't worry about that right now because it's not going to help you.


Please try to telnet to the telus server on port 25 and let me know if you are using an SMTP connector.  See my post above.

If  you do not have an SMTP connector, right-click on connectors and create one.  Specificy the telus SMTP server as the smart host.  On the address space tab, create an address space of *.  Check all other options and make sure you agree with them.

I'll be offline for a couple of hours but will be back soon.

another possible problem:

C:\>nslookup
DNS request timed out.
    timeout was 2 seconds.
*** Can't find server name for address 192.168.0.1: Timed out
Default Server:  lithium.ab.tac.net
Address:  209.115.152.130

Commented:
Do you have your telus server listed in your DNS of AD?. If not you need to tell AD's DNS where and what the Telus server is. Add a zone or a MX/Host record for that server (192.168.0.1)

I am pretty sure your problem is in DNS and the fact that your AD DNS cant see your Telus server. Exchange needs to know where to send the mail to and it uses DNS resolution for that.

It looks like your DNS is OK if you can successfully telnet smtp.telus.net by its name. Why not use DNS for outbound mail delivery?

Don't worry about the error on NSLOOKUP, it just means you have no reverse lookup zones configured on your dns server.

To test whether you can send mail via smtp.telus.net using telnet, do the following:

Telnet into smtp.telus.net on port 25
type:

helo yourdomain.com <Press Enter>
mail from: you@yourdomain.com <Press Enter>
rcpt to: someone@anotherdomain.com <Press Enter>
data <Press Enter>
subject: test <Press Enter>
test <Press Enter>
. <Press Enter>
quit <Press Enter>

Whenever a message is sent, it automatically goes into the "undeliverable message" queue.

drev001 - helo is an unrecognized in my command prompt
 

Commented:
You have to type helo etc. actually within the telnet session, not the command prompt. You may not see what you're typing if the local echo is off
