RFC problem server 6.0.1 CF2

(I set this email on 4 and 5 forum by mistake :))Hi.

I have big problem. I have some email address and I can’t send email to this people. When I send email, I get Delivery Failure Report:

Your document: test

was not delivered to: name.surname@domain.com

because: Error transferring to mail.sprint.com.PL; SMTP Protocol Returned a Permanent Error 550 Sender verify failed

I get information I have a problem with RFC in my server. What should I do to can send email to tih person? what should I set in server document?

Google is your friend:

Usually this error means that your DNS configuration is not correct. The MX record should point to your mail server’s host name (not an IP address) and there should be an A record for that host name. The same issue might also arise, if mail is routed to the Internet through a third party server and that server’s domain is different from your domain name.

That’s the big picture and reflects my in fact very limited knowledge on the topic.

Check that your server is using DNS correctly. Ensure that the line

DNSServer=xx.xx.xx.xx, yy.yy.yy.yy

is in notes.ini as this let’s the server know which DNS server to use when resolving mail addresses.

xx.xx.xx.xx is the primary dns server

yy.yy.yy.yy is the secondary dns server.

Thanks for your answer, Adam. I check server notes.ini and I didn’t find line DNSServer=xx.xx.xx.xx, yy.yy.yy.yy.

Should I set this line in the notes.ini ?

Who is the sender of this Delivery Failure Report?

As I got it, this is not a matter of your server not being able to route mails to the recipient, but the recipient’s server refusing your mail, because it could not verify the sender. Also, the Notes.ini parameter DNSServer should usually not be necessary, if the underlying Operating System’s TCP/IP stack is configured correctly. See:

Again, I must admit, that I’m no expert in this field.
