What is a Mail Mirror?

Mail Mirroring is a quick way to create forwards for an entire domain.

For example, if you have 10 email addresses set up at example.com, you could create a mail mirror at blog.example.com. If you then send an email to any of those 10 addresses at blog.example.com (such as user@blog.example.com), they are automatically forwarded to the corresponding email at example.com (user@example.com).

Please note that you cannot log into any address at blog.example.com since it doesn't exist. The mirror just forwards to the real email address.

A note about DNS

This feature can only be used if example.com is using DreamHost to host its mail. If example.com is using Anti-spam filtering at DreamHost, you must also enable it for blog.example.com as well.

Creating a Mail Mirror

  1. Navigate to the (Panel > ‘Mail’ > ‘Custom MX’) page.
  2. Click the Edit button to the right of the domain you want to create a mirror for. This domain will probably not have any email addresses created. You're going to use this domain to Mirror the domain that already has email set up.
  3. On the next page, scroll down to the 'Mail Mirror' section.
