You can easily connect your domain to Google so that you can use Google Mail and Apps
This assumes your domain is registered through Irish Domains and is active on our name servers a.dns.ie and b.dns.ie
1. Log in to your ID.IE account and locate DNS for your domain.
Navigate to https://id.ie and click "My Account" at the top-right of the page
Log in with your mail account email address and password.
On your dashboard, click "Domains" in the top menu, then click "Manage DNS"
Locate the domain you wish to connect, and click the "Edit" icon on the right
2. Check if there are existing mail related records you need to remove
If you have existing email service, you may need to remove the records for that so that they will not conflict with your Google service.
For example, existing Irish Domains email service will create an MX record, a SRV record, and a TXT (SPF) record on your domain - these should be removed.
3. If you need to validate your domain with Google, add a TXT record containing the validation code provided (by Google)
Add a new TXT record as follows:
@ TXT 3600 "google-site-verification=somereallylonglistofcharactersandnumbers"
4. Now add the 5 MX records as specified by Google
@ MX 3600 1 ASPMX.L.GOOGLE.COM
@ MX 3600 5 ALT1.ASPMX.L.GOOGLE.COM
@ MX 3600 5 ALT2.ASPMX.L.GOOGLE.COM
@ MX 3600 10 ALT3.ASPMX.L.GOOGLE.COM
@ MX 3600 10 ALT4.ASPMX.L.GOOGLE.COM
5. Save the changes
Allow up to an hour for the change to take effect, then you can validate your domain with Google and set up mailboxes etc. as needed.
