What do the IIS SMTP protocol logs show? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Posted At: Wednesday, September 21, 2005 1:29 PM Posted To: swynk Conversation: Wrong MX lookups? Subject: SMTP errors
Hi Since installing a SMTP connector on Exchange 2K3 SP1 I have been intermittently receiving the following error: 'You do not have permission to send to this recipient. For assistance, contact your system administrator. <JAX-MBH-01.crowley.com #5.7.1 smtp;550 5.7.1 Unable to relay for external address. These are addresses that have been working in the past. Message tracking shows a NDR created after smtp:started outbound transfer of message. Some times I can duplicate the error when I test. While other times it will work when I test it. I suspect that the problem is at my end, but don't know how to attack this problem. I have a Exchange 5.5 IMC I just tested one such address. It failed when I tested it. A telnet to the smtp server worked just fine. So I tested it again from Outlook and of coursed it worked. This is driving be crazy. Any help would be greatly appreciated. My searches haven't turned up any thing that would seem to cause this problem.
