This topic describes how to add multiple domains and domain aliases to your Alibaba Mail service.
Domains
A domain is the part of an email address after the @ symbol. Alibaba Mail allows you to add multiple domains. For example, if your company owns both example.net and example1.net, you can add both as domains. When you create a new email account, you can choose to use either @example.net or @example1.net. By creating an alias account, emails sent to both user@example.net and user@example1.net will arrive in the same mailbox.
The maximum number of multiple domains and subdomains you can add depends on the number of paid accounts you have:
If you have 10 or more paid accounts, you can add up to 10 multiple domains and subdomains.
If you have 50 or more paid accounts, you can add up to 30 multiple domains and subdomains.
If you have 500 or more paid accounts, you can add up to 100 multiple domains and subdomains.
Paid accounts are sub-accounts and do not include the postmaster account.
Note: The AI Premium Edition is not subject to these paid account limits and supports up to 100 multiple domains and subdomains by default. For more information about feature differences, see Product Editions.
Add domains
To use the multiple domains feature, you must have at least 10 paid accounts.
The screenshots in this section use an account with 10 paid accounts as an example.
Sign in to the mail management console with the postmaster account. Navigate to Enterprise Customization > Domain Management > Domain Settings. Click Add Domain, enter the domain that you want to add, and then click OK.
After adding the domain, you must configure its DNS records. Click View Details, and add the CNAME, MX, and TXT records as instructed.
NoteYou must configure the domain name resolution with your DNS provider. For an example using the Alibaba Cloud DNS console, see How to set up DNS resolution for an Alibaba Cloud domain to use with Alibaba Mail.
After you add the DNS records and they propagate, the status changes to Normal, and the domain is ready to use.
NoteDNS record propagation depends on your DNS provider. DNS record propagation can take from a few minutes to 48 hours to complete globally. During this time, the status shows as Verifying.
Delete domains
Warning: Deleting a domain is an irreversible action. All accounts and emails associated with that domain will be permanently deleted. Before proceeding, check for active accounts under the domain. If you need to preserve account data, change the domain for those accounts first. To learn how, see How to edit employee account information.
Each domain you add is unique. If you delete a domain and then add it again, you cannot restore the previously deleted accounts from the Account Recycle Bin. You can, however, back up emails by transferring them before deletion. For more information, see What is the Account Recycle Bin.
Find the domain you want to delete, click More > Delete, and then click Confirm.
After you delete the domain, all associated accounts and emails will be permanently removed.
Add domain aliases
You can add up to 6 domain aliases for each primary domain. This feature is not available for the free email service.
Sign in to the mail management console with the postmaster account. Navigate to Enterprise Customization > Domain Management > Domain Settings. Find the primary domain to which you want to add an alias, and click More > Add domain alias.
Enter the domain alias you want to add and click OK.
After adding the domain alias, you must configure its DNS records. Click View Details and add the CNAME, MX, and TXT records as instructed. After the DNS records propagate, the status changes to Normal, and the domain alias is ready to use.
NoteYou must configure the domain name resolution with your DNS provider. For an example using the Alibaba Cloud DNS console, see How to set up DNS resolution for an Alibaba Cloud domain to use with Alibaba Mail.
Delete domain aliases
Find the domain alias you want to delete, click Delete next to it, and then click Confirm.
FAQ
The primary difference is how alias accounts are handled.
With multiple domains, you must manually create an alias account for each user. With a domain alias, the system automatically creates an alias account for every user.
