Outgoing Mail queueing in exchange server 2003

343 Views
Last Modified: 2013-11-30
Last week I had some issues with our server as our ISP changed the server IP address on us, lots and lots of issues, however we got that sorted, this morning I have realised (after many phonecalls from annoyed employees and the boss) that emailsare not going out. Ive opened up the exchange manager and sure enough 40+ emails sitting in queue. What can i Test? Router has ip filter set for SMTP to open port 25, there is an SMTP connector setup in exchange, what can i do, really need this sorted ASAP.

Thanks in advance.

How many server do you have ?
Do you have all in the same box : Domain controller and Exchange server ?

Do you have the dns service installed ? A reverse DNS lookup zone ?

Incoming mail is fine, outgoing to outside of domain not going, but inside the domain is going.

Are you using your exchange server to surf Internet ? This is a valid link :)
Try to copy/paste

Am i adding an external DNS in there? Also there is nothing located in the SMTP connector, I have DNS running as I found it, when I click Check DNS in the advanced window of the Default SMTP server tree it says the domain name is not valid

Yes put external DNS here. Your DNS IPS is best.
Another one :

80.10.246.2
80.10.246.129
193.252.19.3
193.252.19.4

What does doing that process actually achieve? Internal emails are still working, but not outside.
Because the static IP changed is there something in the DNS or exchange that also needs to be changed for the updated of tis ip address.

The exchange server will use External dns to resolve address and found MX server to send email. When you've mail in queue sending are not immediate but you can force by right clicking on them.

You say your static IP change but which one ? WAN IP ? LAN IP ?
I'm waiting answer from thos question too :

To know if you've DNS server installed go to Administration tools, you should see "DNS"
But assuming you have Exchange server installed I should have one installed but perhaps not on this server. You need to set the DNS to the right internal DNS.

Open networks connection, double click on you NIC, click on properties, click on TCP/IP version 4, modify the DNS to your domain controler IP address

ok so ill just wait 10 minutes?

Commented:
the DNS server is the domain controller, it was our WAN IP that was changed.

Have rung ISP and they have all correct details. All mail goes through trendmicro. As a temporary solution can I set users up on pop3? If so how do I set this up server side as it's currently not activated. Thanx

Don't use POP. Awful protocol which will result in the loss of email.
Can you actually do any name resolution? Telnet to remote servers?

telnet maila.microsoft.com 25

Telnet to your ISPs SMTP server if they make you do that?

Did you change the Exchange server DNS setting with the IP address of your domain controller ?
We need to have a good DNS server before starting send mail.

Telnet is just a way of testing SMTP connectivity - it is telnet the application, not telnet the protocol.

I understood that Mesha. For this test I would propose :

telnet 205.248.106.64 25
or
telnet 131.107.115.212 25

Commented:
Leakim can you explain in lamens terms what you mean by changing the exhange servers DNS setting with the IP address of the domain controller? As i contact the domain controller and asked them to make sure they had the correct IP address for our DNS already, this is why I asked about the router filtering.
When I conduct a test with telnet from command prompt on the server side, is the test you are talking about in your last post?

Thanks again.
