How inbox domains work
Every Comail inbox belongs to an atproto account. You sign in with that account, choose an available email address, and Comail records the address as belonging to your DID, the durable identity underneath your handle.
An @comail.at address does not require you to buy or configure a domain. Inbox signup is currently limited, and you may need to join the waitlist before you can claim an address.
Over time, other domains can become available to the same atproto account. These fall into two broad groups:
- Personal domains: a domain you bring for your own email, such as
you@yourname.com. - Community domains: a domain whose owner makes addresses available to a group, such as
you@community.example.
How a domain becomes available
Section titled “How a domain becomes available”A domain owner decides who can request an address. They can make the domain available:
- to any atproto account;
- to a specific list of atproto accounts; or
- to accounts hosted by a particular PDS.
Comail checks those rules against the DID you signed in with. Eligible domains can appear alongside @comail.at when you choose an address. Availability depends on the current rollout. Some domains can be claimed immediately; others require approval from the domain owner.
Access follows your atproto account. Changing your handle does not change the DID that owns the mailbox.
What happens to your original address?
Section titled “What happens to your original address?”Getting access to another domain does not erase your @comail.at identity. One atproto account can use the addresses it is eligible for.
Community and custom domains are being introduced gradually. The address picker will show the choices currently available to your account; you do not need to manage a separate login for every community.
