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 sales@mydomain.com, support@mydomain.com, accounts@mydomain.com, but without adding extra users on your account.
To set up a catchall alias:
- Go to Settings → Users & Aliases.
- Create a New Alias.
- Set the email address to be
*@<domain.tld>. - Optional: update any other options as required. See the aliases page for more information.
- 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 sales@mydomain.com or accounts@mydomain.com, 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:
- Go to Settings → Users & Aliases.
- Create a New Alias.
- Set the email address to the one you'd like disabled.
- Click Show advanced preferences.
- Fill in the checkbox next to Disable.
- Save the change.
Mail sent to this address will be bounced. Delivery will continue for mail sent to all other addresses at the domain.
