Objective:
This article will teach you how to update your existing domain’s MX records to point to Hushmail if you have a domain registered on Google Domains.
Why you need to set your MX records:
Mail Exchanger (MX) records are the part of DNS records that direct email to specific servers on the Internet. Before Hushmail can receive mail for your domain, you’ll need to configure the MX records.
1. Sign in to Google Domains
2. Go to DNS records
Click Configure DNS on the Domains dashboard beside the domain you want to verify for Google services. Scroll down to the Custom resource records section.
3. Delete existing MX records
Locate the MX records under the Custom resource records section. Click Delete next to each MX record. Repeat the process again until you delete all MX records.
4. Add your Hushmail records to G Suite
From the Type list under Custom resource records, select MX
Leave the Name field blank
Leave the default value in the TTL field
For data enter: 10 plsmtp1.hushmail.com
Click on the + icon
Add the second MX Record:
Type: MX
Leave Name blank
Leave TTL as default
For data enter: 10 plsmtp2.hushmail.com
Next step:
If it says 'record already in use' this usually means that the G-suite records are still there. What you will need to do is go to the 'Synthetic Records' option that's just above the Custom Records and click into the 'Email Forwarding' section. A list of Google records should then appear that you will need to remove.
