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 is set to port 25 is there anything else I should check?
are you able to telnet on any other mailserver (to which mail is going) on port 25.
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.

Simon,
thanks that has worked, do you no if there is a way to test the outbound connection through telnet session? or can I just use the mirosoft web page now to do all my testing?

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.

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,
