Hey all,
We are going to be upgrading our Domino mail server from 6.5 to 8.5. What we would like to achieve first is to create a test email environment. This will be a internal mail server routing with a test domain name using the same external IP address as our live domain. If you are wondering why we want to do this, 6.5 to 8.5 is a big step and our email server is on it's last legs and badly configured. To minimize downtime while we test, we need a working test environment.
realdomain.co.uk (not the real domain name)
MX records:
relay1.mailwash.co.uk (our mail filtering service)
relay2.mailwash.co.uk
NS records:
ns0.bt.net
ns1.bt.net
ns2.bt.net
I have registered a test domain from 1&1. Lets say its testdomain.co.uk
MX records:
mx00.1and1.co.uk
mx01.1and1.co.uk
NS records:
ns67.1and1.co.uk
ns68.1and1.co.uk
Firewall access rules and NAT policies are in place to route the correct MX records to the correct internal mail servers via SMTP. I can send emails from my test domain to my Hotmail account no problems. If I try and send an email address from my Hotmail to an email address I have configured on my test domain I receive a 550 error.
Little more details on the error:
<Init> 220 mx-b.kundenserver.de (mxbap3) Welcome to Nemesis ESMTP server
<Helo> 250 mx-b.kundenserver.de
<MailFrom> 250 OK
<RcptTo> 550 <user.name@testdomain.co.uk>: invalid address
<Quit> 221 OK
I believe this is a DNS issue, unfortunately I am not an expert in DNS. How do I point the MX records point to our external IP address? Do I need to do something with the NS records for our testdomain.co.uk? I'm not sure what to do next. Any help/pointers will be much appreciated thank you.
