Need to know how to configure Reverse DNS on a windows 2000 to stop Reverse DNS mail rejection
Posted on 2005-05-12
I just had a client send me a rejected email message that read as follows....
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<EX-SRV1.Zantis.Zantisworks.com #5.7.1 smtp;554 5.7.1 The server sending your mail [126.96.36.199] does not have a reverse DNS entry. Connection Rejected. Please contact your Dial-Up/DSL/Network ISP Provider. Default Reject!>
I have read many posts about what to do and most of them say "ask your ISP to configure the reverse DNS" which I'm sure that I'm the one that needs to correctly enter this into my server. I have a windows 2000 server running DNS and points the Host and MX records to the correct IP addresses for both the websites and the email. I read the following post.....
<<<<<<<<<<<<<< You cannot resolve this by going to your server. You will need to contact your ISP and have them setup a reverse DNS entry for
your mail server. If your server is 'mail.yourdomain.com', then you need to have them set the reverse IP for 123.45.678.90 to mail.yourdomain.com.>>>>>>>>>>>>
Where in the DNS does this get set? I have tried a couple of entries and haven't set it up correctly yet.
I tired to put some entries in the Reverse Lookup Zones but without any luck. Is this where this would go?
