Add multiple domains and domain aliases

Learn how to add, configure, and manage multiple domains and domain aliases in Alibaba Mail.

Domain names

A domain name is the @-suffix selected when creating a mailbox account. Alibaba Mail supports multiple domains, with the maximum allocated based on account count. For example, if a company owns both example.net and example1.net, an administrator can add both. Users then choose @example.net or @example1.net when creating accounts. The accounts a***@example.net and a***@example1.net are two separate mailboxes.

Note

Multiple domains and subdomains are allocated based on billing account count:

10 billing accounts: 10 domains and subdomains by default.
50 billing accounts: 30 domains and subdomains by default.
500 billing accounts: 100 domains and subdomains by default.

Paid accounts include all sub-accounts, excluding the postmaster.

The AI Premium Edition includes 100 domains and subdomains by default, regardless of billing account count. The Version comparison details feature differences.

How to add a domain alias

What is a domain alias?

A domain alias maps to a primary domain name, allowing all users under it to send and receive emails using the alias. For example, if example.net is the primary domain and example1.net is the alias, a***@example.net and a***@example1.net access the same mailbox. Emails sent to either address are delivered to both.

Note

Each domain name supports up to six domain aliases.

Domain alias

Definition: An alias mapped to a primary domain, enabling shared email access for all accounts.
Scenario: For example, if the primary domain is example.net and you attach the domain alias example1.net, logging on to a@example.net and a@example1.net accesses the same mailbox.

- All users under the primary domain can send and receive emails using the domain alias.
