Are they sending to an internal account or to an external account? If external does it work if they send to an internal account? What client are they using?, if Outlook 2000/XP/2003 etc is it configured to use Corporate or Internet? If POP3 client, is it configured to authenticate with the Outgoing Mail Server?

This is the first time I've had a problem like this at this company with this setup and I'm a little baffled at why I'm getting the error. Your message did not reach some or all of the intended recipients. Subject: various Sent: 10/6/2003 9:19 AM The following recipient(s) could not be reached: email@xxxxxxxxxxx on 10/6/2003 9:19 AM You do not have permission to send to this recipient. For assistance, contact your system administrator. <server.domain.local #5.7.1 smtp;550 5.7.1 Unable to relay for email@xxxxxxxxxxx> I tracked the email and it started outbound transfer of the message but then a NDR was generated. I'm running Exchange 2003. I've double checked the relay settings on the SMTP virtual server and "Only the list below" is checked as is "Allow all computers which successfully authenticate to relay, regardless of the list above." Any help is appreciated! Donavon Yelton Manager of Information Systems Carpenter Industries, Inc.
