Try Telnet to Port 25 to Test SMTP Communication and see if still the error comes then it is definately ur ISP or the reciveing persons mail server which is causing the problem .

If u r able to send the mail , then it is ur mail server which is creating the problem .

Follw the article to see how to test ur smtp communication

For telnet on SMTP you have to use port 25.

Telnet 10.123.1.1(ip of the recipient domain) 25

let 10.123.1.1 is IP of recipient mail server .

Here IP of doamin is IP of Mail server of recipient .

You can find ip of the recipient mail server from network-tools.com.Place recipient doamin and click on lookup.

May you please check TCP port for smtp in your exchnage .Just go to Default SMTP virtual Server.

Go to Exchange Sytem Manager...Administrative Group ...Your Exchange server ....Protocols....SMTP... Default Smtp Virtual Server...Right click go to properties....Dlivery ...Outbound connections...TCP port.Whether it is 25 or anything else.

It sounds like you are opening a telnet session, then entering the command.
That is not the way to do a telnet test.

Open a command prompt - nothing else, and type

telnet maila.microsoft.com 25

If you open a telnet session first, then it will attempt to use the default telnet port - which will be blocked.

ok now for the next problem, I have the email address which is live on the net but why is exchange throwing back this message on an email.
     The destination server for this recipient could not be found in Domain Name Service (DNS).  Please verify the email address and retry.  If that fails, contact your administrator <sbs.lease360.local #5.4.0>.
below is from the log for the tracking.

           
20/06/2006      13:18:34 GMT      -      -      -      SBS      -      Admin@test.com      1027      F9CE5ED33FE23044A2CEA1BFCE1E223771AE98@sbs.lease360.local      0      0      10819      1      2006-6-20 13:18:34 GMT      0      -      c=GB;a= ;p=Lease 360;l=SBS-060620131834Z-9433      -      EX:/O=LEASE 360/OU=FIRST ADMINISTRATIVE GROUP/CN=RECIPIENTS/CN=ELLIOTT.STEVENS      -
anyone?

The NDR means what it says.
The server sending the message cannot find the server in the DNS.

Carry out an MX record lookup on the Exchange server.

For example... microsoft.com:

C:\>nslookup
Default Server:  server.domain.co.uk
Address:  192.168.1.1

> set type=mx
> microsoft.com
Server:  server.domain.co.uk
Address:  192.168.1.1

Non-authoritative answer:

microsoft.com   MX preference = 10, mail exchanger = mailc.microsoft.com
microsoft.com   MX preference = 10, mail exchanger = maila.microsoft.com
microsoft.com   MX preference = 10, mail exchanger = mailb.microsoft.com

maila.microsoft.com     internet address = 131.107.1.7
maila.microsoft.com     internet address = 131.107.1.6
mailb.microsoft.com     internet address = 131.107.3.123
mailb.microsoft.com     internet address = 205.248.102.77
mailc.microsoft.com     internet address = 205.248.102.78
mailc.microsoft.com     internet address = 205.248.102.79
>

When you have the MX server information, see if you can telnet to port 25 of the remote server.

For example (using the above information)
telnet maila.microsoft.com 25

Simon,
I have tried what you have sent me and it throws back the correct server and ip when I type
> set type=mx
> microsoft.com
Server:  server.domain.co.uk
Address:  192.168.1.1
i get a completly different different response from what you have sent. Also it is only effecting 4 internet email address at that service is there anything that I could be missing in exchange to do with filters, senders, reciepts?
Also I did some checking on Microsoft found this below,

That was just an example for microsoft.com
Did you try it with the domain that you are having problems with?

Does your email go out directly, or via a smart host?

I also notice that your server is announcing itself as sbs.lease360.local. That isn't valid on the internet and may cause problems with email delivery. Get it changed to match the what the server is known as on the internet.
