如何为AWS WorkMail配置完整域名邮件自动重定向？

Great question! You don’t need to manually create aliases for every user one by one—AWS WorkMail has a built-in feature that lets you map your entire example.org domain to your existing example.com organization, automatically setting up matching aliases for all users (and their existing aliases) in one go. Here’s how to do it:

Step 1: Add example.org as an Alias Domain in WorkMail #

Instead of adding example.org as a standalone domain (which would require recreating users), add it as an alias domain for your existing WorkMail organization:

• Log into the AWS Management Console and navigate to the WorkMail service.
• Select your existing organization (the one hosting example.com accounts).
• From the left-hand menu, go to Domains, then click Add domain.
• Enter example.org in the domain field, then select the option labeled Add as an alias domain (this is critical—don’t skip this).

Step 2: Verify the example.org Domain #

WorkMail needs to confirm you own example.org:

• If your domain is hosted in Amazon Route 53: Click Add records to Route 53—AWS will automatically create the required TXT verification records for you.
• If your domain is hosted elsewhere: Copy the provided TXT verification record and add it to your domain’s DNS settings through your external DNS provider. Wait a few minutes for DNS propagation (usually 5-10 minutes, but sometimes longer).

Step 3: Confirm the Setup #

Once the domain is verified, WorkMail will automatically:

• Create a matching user@example.org alias for every existing user@example.com account.
• Extend this to any existing aliases: For example, if admin@example.com has an alias support@example.com, WorkMail will automatically add support@example.org as an alias too.
• Apply this to new users: Any accounts you create in the future will automatically get both user@example.com and user@example.org addresses.

Now, any email sent to admin@example.org (or any other user/alias combination on example.org) will land directly in the corresponding example.com account’s inbox—no manual alias setup required!
