You can disable edns-0 without any harm.

 

However, if NO e-mail is getting through, that isn’t the problem. EDNS-0 almost always affects only large sites (like yahoo, excite, aol, etc.)

 

Enabled details smtp protocol logs and see what they say.

Hi Guys,

 

any input on this would be greatly appreciated. We can telnet the smtp relay box, but nothing seems to get through. everyone seems to think this is not thier problem. Somehow we feel it is the ISP's but they are not taking responsibility for this.

 

Any Ideas please

Hi,

 

Someone recommended we do the following. Not quite sure this does. Please advice

 

Turning off EDNS-0 extended UDP packets in W2k3 server's DNS.

(EDNS0 as defined in RFC 2671)

Server 2003's DNS server has a new capability, it can handle UDP packets greater than 512 bytes. Unfortunately some firewalls cannot pass these packets so it is desirable to have the DNS server fall back to TCP in this case as it used to do in previous versions of NT DNS.

To turn off the EDNS-0 feature run this from a command prompt:

dnscmd /Config /EnableEDnsProbes 0

Once you run this your W2K3 DNS server will never advertise its EDNS capabilities and so will never receive a UDP packet > 512 bytes.

dnscmd.exe can be found in the Support Tools.

To install Windows Support Tools

  1. Insert the Windows CD into your CD-ROM drive.
  2. Click No if you are prompted to reinstall Windows .
  3. When the Welcome screen appears, click Perform additional tasks, and then click Browse this CD.
  4. Go to the \Support\Tools folder.

For complete setup information, refer to the Readme.asp file available in this folder.

  1. Double-click suptools.msi.
  2. Follow the instructions that appear on your screen.

If your able to receive and send mails through other domains…still you need to have a look at the below points.

 

Network connectivity issues you can check using trace route to the problematic domain.

 

Find out with remote domain administrator if your domain has block listed in there Database

 

Try telnet from your exchange server to Remote domain (C:\telenet problemdomain.com 25 )

Hi,

 

Please have a look at the below, it can be any of the below issue.

 

1)       Network connectivity issues

2)       You might be blocked by Remote server

3)       Try to telnet 25 to the remote server and see what the response you can see?

4)       Do you use ISP Smart Host for delivering Emails or you got own SMTP server?

5)       Finally Check the DNS. ( check FQDN is valid for SMTP Virtual server)

 

If the issue will not resolve please increase the Diagnosis logging for MSExchange Transport.

 

 

Cheers!!!

Prabhu

Subject: [ExchangeList] NDR 4.4.7 Could not deliver the message in the time limit specified

 

Hi guys,

 

Not quite sure why this is happening. But we can send emails to people ok, but we are having problems from a particular domain. Other domains can send to us ok.

 

When we send a mail to the domain it arrives ok, but users can not reply to our message. They keep getting the 4.4.7 NDR with message delayed and then timeout.

 

If anyone can point us in the right direction it would be helpful, cos a lot of steam and trouble is brewing over this.

 

Windows 2003 Domain, Exchange 2003 SP2. Mail Marshall for filtering.

 

Thanks
