I recently had to set emails up for a client through 123Reg and had no luck finding 123Reg’s MX records if you wanted to use your own, custom nameservers.
For consistency across our hosting clients, I wanted to point the nameservers for the client’s domain name to our systems, and then alter the MX records for email at our end. There is a guide on 123Reg.co.uk for setting your MX records up using their nameservers, but not any guides if you want to use your own nameservers, so after quite a bit of digging I found them (in this thread on cPanel’s forums).
So, I wrote this quick tip up to prevent the hour of swearing and head-scratching I’ve just endured:
Of course, there are a couple of caveats to using your own nameservers and pointing MX back to 123Reg this way:
- 123Reg could change their MX records and screw your emails up, but I think this is pretty unlikely!
- It’s a good idea to know what you’re doing. 123Reg.co.uk has a (basic) guide to MX records
