Exchange server do not receive emails

Hi,

You need to define mx records for your email server. For examle if your domain is 'halo.com' your mx record must be created with the <pc name>.halo.com, something like mail.halo.com.

you can see if your mx records are in place by doing a nslookup.

At command prompt type Nslookup

set q=any
<your domain name here>

once you enter this if your settings are done correctly, you should see the records for your site. Best to do this from outside your network.

There may be many reasons why you may not get emails. If the DNS servers were only configured right now, the settings take upto 48 hours to propagate. Your server may not be set up properly. Your firewall or router may need to be set up. We would like more information about your environment.

In windows you can type 'telnet mail.halo.com 25' and use the telnet facility from there. Here what you type will not be visible.

You can also just type Telnet and enter at command prompt to get a different Telnet facility.

We use putty.exe to Telnet. It is very easy to use and you can see what you type.

Upul

it is not a DNS problem, the server can be reach from outside without problems.

could you give more background information. Is there a firewall? Is there a router? Are these configured?

Have you set up the Mail Protocols in Exchange?

It's a bit tough without the exact details as to how you had set up exchange and your environment info....

You can also use the dnsreport and email test to check for errors. At www.dnsreport.com, if you could post your domain, we could check from outside.

thx for all the help, the problem was that we were using freeproxy and this program was blocking the port 25.
