Ok,  Thank you - the additional A record you recommended is what I needed to create mail.domain.tld which opens the mail server's control panel. I think the only other thing I need to figure out is the reverse look up.  You said "Be sure that if you need reverse DNS that varies from whoever provides your CIDR block, your upstream provides and allows that also.". How can I test this and I'm not sure how to create a reverse look up. Thanks again for all your help! ------------------------ Keith Smith --- On Fri, 7/8/11, Lisa Kachold wrote: From: Lisa Kachold Subject: Re: Zone Edit MX record config.

Be sure that if you need reverse DNS that varies from whoever provides your CIDR block, your upstream provides and allows that also.   I want to make sure I have the mail server configuration correct.  To get to the mail server control panel we use mail.domain.tld.  Dig gives me the IP of the mail server.  So in Zone Edit I created a record of type MX, set the sub-domain to "mail", TTL to 7200, Preference 10, and host to the IP Address of the mail server. There are actually two records involved in setting up the mail server: A record pointing hostname to IPADDRESS MX record setting precedence for mail delivery for the domain that points to the hostname. Be aware that the hostname must match in mail for the RFC to be valid. nslookup >set type=mx > mail.mydomain.com Should give you information that matches your new DNS.
