A catch-all address receives email sent to any username at your domain that does not have its own mailbox — for example mail to anything@yourdomain.com.
Enable catch-all
- Go to Advanced Features → Catch-All E-mail.
- Select the domain.
- Choose the destination mailbox for unmatched addresses.
- Save the setting.
Security consideration
Catch-all addresses receive large volumes of spam sent to random usernames. Many administrators prefer disabling catch-all and creating only the mailboxes they need. If spam becomes overwhelming, disable catch-all and use specific forwarders instead.
