Dear all
I wonder if any of you guys and gals can help me out.
I have set up a small email network using windows 2000 with exchange 5.5. I have a public DNS MX record set up and a linksys cable router to forward all port 25 requests to my exchangeserver. The mx record points to the public IP address given by my ISP which is currently the router. The system recieves email okay to my domain. However when I send out email it gets stuck in the outbound mail queue. Now I know this would happen ifthe DNS is not correct. But I have added the correct DNS suppiled by my ISP. So not to sure what to do next. Any help would be appreciated. Any exchange guru's out there?????

I had a similar situation. The problem that I had was that the Mailbox was set up for internet mail and the user account was set up for POP3. Hope this helps.

Parden my stupidness but can you provide more information I don't quite see how I would check for this.
Thanks for your help

ofcourse DNS works because you can surf the web on the exchange server. Now Exchange also requires the server to have a fully qualified domain name. I would check this.

Right click "MY computer", properties, computer name tab, change, more..., input your domainname.com in the "Primary DNS suffix..." field. I think you can also find this in the advanced button, DNS tab, of the tcp/ip properties of your NIC.

Stop and restart the Exchange Internet mail service. Check the queue.

PS: Always check your logs. If this doesn't help, you can try to delete the internet mail conenctor and recreate it. Reject this if it doesnt help, so I can think about it more.

I checked that before and it's all fine. Thanks anyway. However according to the event logs i get this :

A timeout occurred while trying to deliver mail to ??.??.??.?? (for domainname.com). Undelivered mail will be retried later. The timeout occurred while waiting for a response to the HELO command.

and logs : Event id 4041

??.??.??.?? is the actuall Ip address

Any clues?

try to connect to ???.???.???.??? using telnet on port 25

example to connect to microsofts smtp server:

start run --> telnet maila.microsoft.com 25
or by IP
start run --> telnet 131.107.3.124 25

You should get back this:

220 inet-imc-02.redmond.corp.microsoft.com Microsoft.com ESMTP Server Thu, 26 Se
p 2002 09:36:01 -0700

If you don't then you have a firewall issue.

You right it was a firewall issue. I figured that out last night. I turned it off (shock horror) only for a second and it was fine. I already tried the telnet thing a few days before and it was fine. Problem I have now is, which is a totally new ball game is what ports do I need to set up to allow outgoing email on the firewall. Port 25 is enabled and that fine. Is there another port that i need to enable. Currently using norton personal firewall. At the email is in a test environment.

Thanks guys for all your help.

open up port 25 for smtp mail
open up port 110 for pop3 mail if you want users to use internet email from home or remote locations.

25 is the only port needed for exchange to communicate over the web with other servers.

I check in that document I done all that already. Still it provided useful reading. There must be something in norton that stops the sending of outbound email.. As if I turn the firewall off it sends okay.
