[Modus] Weird NDR?

[Del Hines]

The DNS cache on the mail server may be corrupt.  You can sometimes test this by doing a ping instead of a nslookup. If this is the problem, an “ipconfig /flushdns” should correct it.   - Del   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Robb Bryn Sent: Monday, November 17, 2003 11:07 AM To: [EMAIL PROTECTED] Subject: [Modus] Weird NDR?   I'm getting an NDR for the following address - [EMAIL PROTECTED]   The server reports a DNS failure but it resolves just fine from NSLookup (even tried from the server itself).  I am able to telnet to the destination mail server (tlcfl.com.mail5.psmtp.com:25) with no problem.  Where else can I look?
