Catchall/Wildcard aliases

Looking for general information on aliases?

A catchall or wildcard alias is one that allows all mail to any address at a domain to be filtered into a single account. You can then use rules based on the To address of a message to sort mail into separate folders if you need to.

These types of aliases are useful if you'd like to have separate mail identities for,,, but without adding extra users on your account.

To set up a catchall alias:

  1. Go to Settings → Users & Aliases.
  2. Create a New Alias.
  3. Set the email address to be *@<domain.tld>.
  4. Optional: update any other options as required. See the aliases page for more information.
  5. Click Save.

Creating an alias also creates a matching sending identity. This means you can also send mail using this wildcard alias. When sending from a wildcard alias, you'll be able to manually type the From address (to or, etc) when writing a message.

If you only have a few addresses you receive from and send to, it may be easier just to set up individual aliases that will have matching sending identities.

If you have both a wildcard alias and a specific alias, incoming mail will send to the specific alias.

If you want to stop receiving mail to a specific address at the domain with a wildcard alias set up, you can disable that one address. To do so: 

  1. Go to Settings → Users & Aliases.
  2. Create a New Alias.
  3. Set the email address to the one you'd like disabled. 
  4. Click Show advanced preferences
  5. Fill in the checkbox next to Disable
  6. Save the change. 

Mail sent to this address will be bounced. Delivery will continue for mail sent to all other addresses at the domain.
