The wildcard email address is the account's catch-all address. This means that any email sent to your domain that is not yet set up to be an email account or an email alias will be sent to the wildcard address for your account.
This allows you to catch any emails sent to the misspelled email address. Please keep in mind that a catch-all address can be redirected to one email address only.
First of all, make sure you have switched your MX records to free email forwarding according to this article.
Once the MX records for free Email Forwarding are set, you need to set up a catch-all (wildcard) email address in this way:
1. Sign into your Namecheap account.
2. Select Domain List from the left sidebar and click on the Manage button next to your domain:
3. Scroll down to the Redirect Email section and click on the Add catch all button:
4. Enter the destination email address in the Forward to field and click on the checkmark to save the changes:
Once you save them, the following message appears:
NOTE 1: You can create up to 100 forwarding email addresses when using our BasicDNS.
NOTE 2: Delivery of test emails sent from the same email address that is set as Forwarded to will most likely fail. Thus, use another email address when testing email forwarding.
