Exchange 2003 NDR message: You do not have permission to send to this recipient
I have a vendor that seems sometimes seems to be getting this messages when they send emails to our email servers.
We have an Exchange 2003 Server and we use Postini for inbound/spam filter.
User1@mydomain.com is the user that we hos in our Exchange ORG.
This is the email that they get when the message is bounced back.
Your message did not reach some or all of the intended recipients. Subject: RE: commercial Sent: 3/15/2012 11:05 AM The following recipient(s) could not be reached:
firstname.lastname@example.org on 3/15/2012 11:05 AM
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<mail.ocrra.org #5.7.1 smtp;550 5.7.1 Requested action not taken: message refused>
The only thing that I am getting is that through DNSSTUFF then SPF test returns "permerror"
Error code 5.7.1 may occur if one or more of the following conditions are true:
•The sender of the message does not have the privileges that are required to complete delivery. = The sender has been able to send to this particular email address before, sometimes the emails go and sometimes they just fail.
•You try to relay your mail by using a second server, and the second server does not let you relay mail. The remote server returns a 5.7.1 error code. = We only have a single SMTP server (cluster resource)
•You do not have a recipient policy configured for the domain to which the message is sent. = We don't
•The recipient has mailbox delivery restrictions enabled. For example, the recipient's mailbox delivery restriction is configured to only receive mail from a specified list. Other mail is rejected. = No restrictions
•A distribution list is configured to restrict mail delivery to messages from authenticated users. Mail that is sent from an anonymous session is rejected. = No distribution list is configured.
•Your Exchange computer is on an unsolicited commercial e-mail list. Your Exchange computer may be listed as an open relay. = We have checked DNSSTUFF and we are not, the RBL test seems ok.
•The fully qualified domain name (FQDN) name of your Exchange computer ends with ".Local". - Our FQDN is exchange.domain.local
•The Allow all computers which successfully authenticate to relay, regardless of the list above check box is not selected on the SMTP virtual server.
•Anonymous access to the SMTP virtual servers is disabled. = In our case is enabled
