How do I correctly setup a domain on 123-reg for use with exchange

Hi all,

I'm taking over ownership of a domain that points to an exchange server. I've not setup a domain that's been used for this before. Normally I just point the nameservers to an NS address of my VPS and my VPS handles it all for me.

This domain needs to relay email to the exchange server and also allow the website to be accessed and hosted by my VPS.

Can someone please explain me how, using 123-reg, I can setup the domain to do all this when it's transferred to me?

You need to set the DNS entry for www t your web server, then further down on the same page change the MX entries to your mail server...

Compaired to the example above you may want to take out the @ entry

Also, what are the mail1, 2, 3 and owa for?

CuteadderCommented:
The @ says where the domain points - mail, web, everything...

the mail1, 2, 3 are just host names for my mail servers then relating to IP addresses...
they can be called anything but mail1, 2 ,3 seem easy...

the owa entry is where I have my Outlook Web Access web server...

So, I need to remove the @ record. Add a www record to my Web Server's IP address. And then add an MX record to the IP address of the server? Does it matter if I only have one MX record?

It doesn't matter if you only have one MX record but for failsafe you may want another one...
i.e. if you have another Exchange server in your company

If for any reason other companies mail servers can not reach the first MX server they will look at the next one (note the priority of 10 & 20)

I user the mail forwarding services of 123-reg in case my mail server goes down to forward to my yahoo email account...

This didn't actually work correctly. I cannot access my website from http://domain.com, I can only access it from www.domain.com.

If you're still reading this post Cuteadder, could you please help?

ok, try it with a @ host A record pointing towards the same ip as the www record - not at my desk so can't compare it right now for you, test your email after you make the changes... I'm sure 123 advise you against it but if you look at mine it's all working...

Let me know the result

123-Reg advise against using @ as a CNAME, but not an A. I think that must be the solution, thanks mate!
