Hi,

I have a question regarding re-pointing the email for a domain.

The website is hosted on one server and the company has their own email server.

Using EasySpace this is the present config:

http://65.38.105.134/~dev/dns_domain.gif

My question: I need to point all email for the domain to an IP number, say: 216.36.09.1
What needs to be done and what would be the syntax to enter?

Thanks for your help,

Al

Hi Al,

You will need to update the MX records to point to the new mail server (or servers). MX records should point directly to an IP so I would advise creating an A record for each mail server (mail1.serverdomain.com, mail2.serverdomain.com for example) and then update the MX records to refer to these newly created entries.

Due to the DNS propagation period I would create the A records first, wait 24 hours, and then update the MX records.

Cheers Dan,

So my clients mail server will have a name such as mail.serverdomain.com - I'm not 100% about that - I just have the IP number 216.36.09.1 - can i set up the A record with just the IP ?

How do refer an MX records to an A name?

Thanks,

Al

ps. sorry for the noob questions. I have a few of these domains to update so hopefully I'll quickly advance beyond noobdom.

Hi Al,

Because you only have the IP address for the mail server you need to create a valid DNS entry to replace nicmail3.iomart.com entry that already exists. To do this create a new A record called something like mail1 and point this to the 216.36.09.1 IP address. Once this has propagated, i.e. you can ping mail1.yourdomain.com and it resolves correctly to 216.36.09.1, then you can add mail1.yourdomain.com as an MX record to replace the nicmail3.iomart.com server, I would suggest adding the new MX record with a preference of 8 (well anything less than 10) and then testing the whole thing.

Give me a shout if you're still stuck!
