You make sure that you have a reverse lookup zone with a PTR record for your Exchange server.

If the receiving domain is doing reverse lookups, they may not accept mail from your domain.

About DNS, actually I got this error from one of the domain I was send mails. "The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator. <mail.ubl.com.pk #5.0.0>" thanks & regards. -----Original Message----- From: Baker, Jennifer [mailto:[EMAIL PROTECTED]] Sent: Wednesday, April 10, 2002 2:22 PM To: Exchange Discussions Subject: RE: DNS Q172953 Once again, vague.

Post your problem in detail and what you have done to try and solve your problem. -----Original Message----- From: Irfan Malik [mailto:[EMAIL PROTECTED]] Sent: Tuesday, April 09, 2002 9:32 PM To: Exchange Discussions Subject: DNS Dear List, How can one check that the DNS is configured properly for exchange server?
