Migrate mail services to Google Domains and Google Workspace

Added by shugo (Shugo Maeda) about 1 month ago. Updated 18 days ago.



Currently mail services of including mailing lists are running on an aged server, and we have to replace it.
We are planning to migrate the mail services to Google Domains and Google Workspace (Google Groups).

The maximum numbr of Google Domains email aliases is 100, but currently has 153 email aliases, so we have to reduce them.
The number of active committers listed in email.yml is 58.

Not sure if this applies to your situation, but a very quick warning based on my own experience: we use a Google Domains email address to send a fairly low volume of transactional emails, and that's enough to trigger Google's automated filters. Every 30 days the account is auto-disabled because "It looks like it was being used in a way that violated Google's policies" and I need to manually re-enable it.

So if you intend to send automated emails (such as commit notifications on ruby-cvs), just be aware that Google Domains is no replacement for email-sending services like Sendgrid/Mailgun.

Thanks for the information.

We are not going to use Google Domains to send emails, but we may reconsider it.

FYI: I migrated to from AWS Route53 to Google Domains today. It remains old DNS records.

We will remove the obsoleted records and prepare email aliases for Ruby core members.

To all the old-time commuters,

Though we have to reduce the mail aliases for a technical reason, this does NOT mean that we will reject your contributions. Just send us a PR to add your email address to and you will be able to commit. We look forward to having you back!
