SMTP #5.7.1 **501** This system is not configured to relay mail fromthought) was a mail server on the other end with the following message: 'st***@company.com' on 11/16/2005 5:20 PM You do not have permission to send to this recipient. For assistance, contact your system administrator. <hermes.domain.org #5.7.1 smtp;501 5.7.1 This system is not configured to relay mail from <internal.sen***@domain.org> to <st***@company.com> for mail.domain.org> This is the same message whether the email was sent by a receptionist or administrator account (of course as luck would have it, it is the CEO who is trying to send this particular message). This only affects this one domain (company.com) that we are sending to, every other domain works out fine. I have checked (what seems like) 100's of technet articles but almost all of them refer to 550 5.7.1 errors and those do not apply to the problems we are having and seem to be for a more broad scope of emails.

I know that several of the Technet articles discuss many 550 issues as well as Cisco PIX issues. We have elimiated the PIX issues by trying work-arounds Hi Customer,
Thanks for posting here. Based on my knowledge, NDR 5.7.1 happens when you are trying to relay your mail through another SMTP server and it does not permit you to relay. Actually, the issue is much possibly caused by the configuration in mail server of hermes.domain.org instead of your Exchange Server. Let me explain it as below. After analyzing the NDR you provided, 5.7.1 happens in the following scenario. When you internal user sends a mail to st***@company.com, the mail is first forwarded to mail server hermes.domain.org. And when mail server hermes.domain.org tries to relay this mail to mail server in remote domain company.com, it detects that your Exchange Server doesn¡¯t have permission to relay this mail. That's why 5.7.1 happens. Considering information above, please contact the administrator of hermes.domain.org for more information. Hope this helps. If there is anything I can help further, feel free to let me know. Thanks!
