Getting NDR sending mail to one domain???
Posted on 2004-08-25
Greetings all, I am experiencing a strange error with Exchange or maybe Outlook, not sure, while sending email to one specific client's domain? This is an intermittent problem but only happens with *email@example.com. The message in outlook says:
"Your message did not reach some or all of the intended recipients.
The following recipient(s) could not be reached:
firstname.lastname@example.org on 8/23/2004 6:59 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@example.com>"
I have searched high and low on the internet with no success. One article said to turn of IIS SMTP service, but I can't do that cause I need it for Crystal Enterprise. Any help is greatly appreciated!
