My 2008 server queue folder is not working. I can´t send emails, their´re on the queue folder and nothing happens. I used netstat -ano and I found a lot of dns.exe UDP connections.  What´s that ? Is that right ?

That is completely normal for a DNS server, which you did not specify whether you were running.

But why my emails are stopped at queue folder.
Windows 2008 server with IIS 7
This is my web server.

Could be a firewall issue. Could be a misconfigured setting on the sending side. Could be the ISP is blocking. There are a multitude of reasons why mail may not be getting sent. We'd need to know a lot more about your environment and you've shared very little.

But your question was whether the DNS connections are normal. And if your server is a DNS server, then yes they are. And they would NOT be the cause of your mail queue backing up.
